This makes the test more interesting.Another change to the AP test material is the inclusion of changes to what we know about the Periodic Table. Many different chemical groups are included in the table, which includes every element on earth. This mak es it easy to take a single test multiple choice and figure out the change in specific materials to see which ones have been added or removed.In addition to the addition of new elements, there is also the addition of K-Acids, which allow for different reactions to occur. They react with some other substance and give off various properties.Because of these additions, you will be able to study how each element has changed in relation to each other. You will be able to examine all the tests in the table, and which ones have had their acid-base content changed. This allows you to compare the original to the change. There are over 600 tests in the table now, so knowing which ones are the most important is critical to the success of your AP class.One of the most exciting new changes is that there are some new products to help you with your AP test. We have a new course book, an online quiz book, and a guide to AP Material. Knowing how to take your AP test the right way will make your life easier in an exam setting.

What is it Like to Attend Columbia University

What is it Like to Attend Columbia University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Julia is a New York City tutor and 2012 graduate of Columbia University. She majored in Ecology and Evolution Environmental Biology. Julia specializes inseveral subjects including Geometry tutoring, Statistics tutoring, and Organic Chemistry tutoring. Check out her review of Columbia: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Julia: Columbia is in New York City, of course, so public transportation is excellent. The 1 line on the subway will take you wherever you need to go in Manhattan, and theres a bus that stops at Columbia that goes directly to LaGuardia Airport. As for safety, New York City in general and the Columbia neighbourhood in particular are much safer than people think. Its not the 80s anymore. VT: How available are the professors, academic advisers, and teaching assistants? Julia: Professors and TAs are generally very personable and available, unless your professor is someone really famous, like Jeffrey Sachs. Academic advisers are available by appointment, but arent terribly helpful. If you have a problem with your schedule or your credits or anything else academic, you need to take the initiative. Try to solve it yourself, and if you cant, then go to your adviser with specific demands that they can fulfill. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Julia: The rooms arent great until senior year, but honestly, who cares? Youre in New York City. People pay $1000/month to live in much worse housing than this, and if you dont like it, you can always strike out on your own and live off-campus. The housing for seniors is fantastic, though. The food is pretty bad at Columbia, but you can use your dining plan to eat at the Barnard cafeteria, which is better. All the same, Id advise that you get off the meal plan as soon as possible. I started cooking for myself my sophomore year, and the upshot is that Im a much better cook than most people my age. As for location and socialization that hardly needs saying. If you use your evenings well, youll make tons of friends both on and off campus. Im from New York and even so I can say I had my most thrilling urban adventures while at Columbia. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Julia: The biggest majors at Columbia are History, Economics, and Political Science, but youll find incredibly dedicated and intelligent people in every department. My major was Ecology, Evolution Environmental Biology, which I think is a hidden gem at Columbia. Everyone in the major does a thesis, which gets generous funding from the department. I had the opportunity to do my thesis research in Kenya. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Julia: Making friends at Columbia is easy if you want to make friends. You cant be shy or passive about it. If you dont reach out to people, you could float along in a bubble of solitude and no one will notice. But if you go out, talk to strangers, take part in campus activity, then youll have more friends than you know what to do with. I know I did. There is absolutely no need to take part in Greek life to make friends in fact, Id advise against it, given all the recent scandal with Columbia fraternities. They constitute less than 10% of the undergraduate body and have a poor reputation to boot. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Julia: Not very helpful. If you want an administration that will nurture you and guide you every step of the way, dont go to Columbia. There are millions of opportunities available to Columbia students, but you have to find them yourself. No one will show you the way. Thats not to say that there arent recruiters on campus, but the most aggressive ones are from Wall Street banks, and frankly I think theyre evil. VT: How are the various study areas such aslibraries, student union, and dorm lounges? Are they over-crowded, easily available, spacious? Julia: The libraries are numerous and architecturally beautiful. Be sure to branch out beyond Butler, our most famous and most used library, especially around finals time when it gets crowded. Im personally fond of the Teachers College library, which is great for group study sessions because youre allowed to talk, within reasonable volume limits. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Julia: I dont know what to say about New York City that people dont already know. Its constant excitement. If you want to do something completely new and mind-boggling every single day, you can (though youll exhaust yourself very quickly.) Columbia is in Morningside Heights, which compared to the rest of Manhattan is pretty low-key, though low-key for Manhattan is high-octane compared to anywhere else. One thing Ill say is that not enough Columbia students venture out of Morningside Heights. Theres plenty to do in the neighborhood, but to me it seems the pinnacle of laziness to forgo a short trip on the subway to enjoy the rest of the city. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Julia: Columbia is just about medium-sized in the scale of things: big enough that you can maintain your privacy, small enough that you dont get lost in a faceless crowd. The class sizes never bothered me. Obviously, something like Intro Chemistry is going to be a big lecture class, but all the core curriculum classes are small, as all the really important classes are. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Julia: Columbia is famous for its core curriculum, a suite of classes that everyone must take. Personally, I had a great time with the core curriculum and Ill never forget my Contemporary Civilization class. The professor was much like Socrates, the ancient philosopher about whom we read so much: he questioned everything the students argued. He let no belief go unfounded, no unconscious bias go unmasked. By the end of the class, I internalized him. I interrogate everything I hold dear, and anything that can survive that scrutiny I keep, and anything that doesnt hold up I discard. I think the core curriculum turns you into a very thoughtful person, if youre willing to open your mind and give up your pretensions. Check out Julias tutoring profile.

Adrenal Cortex Secretes Online Biology Tutors Tutorpace

Adrenal Cortex Secretes Online Biology Tutors Tutorpace Adrenal glands are present on the upper border of kidneys. The glands are embedded in adipose tissue. Each gland is covered by a capsule of connective tissue. The hormones produced by them are required for maintaining carbohydrate metabolism, mineral balance and external sexual characters. Each adrenal gland is composed of two regions, an outer adrenal cortex and an inner adrenal medulla. These two differ in their development and function. The hormones secreted by the adrenal cortex are called corticoids (corticoid hormones).Based on their function corticoid hormones are classified as- Glucocorticoids and mineralocorticoids. Glucocorticoids:- The corticoids involved in carbohydrate metabolism are called glucocorticoids. They stimulate gluconeogenesis, lipolysis and proteolysis and also inhibit cellular uptake and utilization of amino acids. The important glucocorticoids in our body are Cortisol, cortisone, and corticosterone .Cortisol prepares our body for after effects of danger situation. It controls the pumping action of the heart and reduces the pain. Cortisone is concerned with preparing the body against any sudden stress. Corticosterone helps the bodys metabolic system to turn amino acids into carbohydrates to use as fuel for many bodily functions Mineralocorticoids: They are the Corticoids which regulate the balance of water and electrolytes in the body. They are secreted by the outermost layer of the adrenal cortex. Aldosterone is the most important mineralocorticoid in our body. It acts on the renal tubules and stimulates the reabsorption of Na+ and water. It stimulates excretion of K+ and phosphate ions

These are usually the most costly per hour but they're also the most cost-effective since your tutor can focus on you every single minute of your tutorial. With hands-on subjects like cooking, face-to-face tutorials are great.Online tutorials are usually cheaper than face-to-face tutorials since the tutor doesn't have as many travel costs and this saving is usually passed onto their students. As long as both of you have a decent internet connection and webcams, you can use programmes like Skype to communicate with your tutors.Group tutorials are the most like your traditional art classes at school. However, if you get enough of you and your friends together, you could always hire a tutor together. With each student sharing the cost of the hour, you can get quite a discount for each s tudent in attendance. Of course, you won't get as much one-on-one time with your tutor, though.While each type of tutorial has its advantages and disadvantages, you need to choose the one that matches your learning objectives and your budget. Everyone can learn to cook, after all, if they have the right tools, resources, and encouragement.

The Ultimate Guide to Backpack Essentials

The Ultimate Guide to Backpack Essentials The below post is the first in our 2017 Back-to-School Series. Throughout the month of August, visit the Varsity Tutors blog for back-to-school advice, tips, and tricks for all ages. Buying backpack essentials is a classic back-to-school activity for every grade level. The basic shopping list for all age groups includes items like pencils, pens, erasers, and paper, but students of different ages will also need to fill their backpacks with different items. So what are the backpack essentials that youll need to prepare for this school year? Here is our ultimate guide to backpack must-haves, broken down by elementary school, middle school, and high school. Elementary school backpack essentials TissuesIllness tends to spread quickly throughout schools. Prevent dripping noses by keeping a pack of tissues handy for your student to grab from his or her backpack. WipesElementary school is full of messy pastimes like arts and crafts, recess, and, of course, lunchtime. Wipes make it easy for students to get into the habit of cleaning their hands after they get them dirty or before they eat. Layers of clothingYounger students typically switch between inside and outside time each day. Teach them what clothes they should wear when they go out for recess, field trips, and when they leave at the end of the day so that they stay warm (or cool). SunscreenThis is something else that students should wear when they go outside. Teach your student how to apply sunscreen, and remind them to reapply it throughout the day if they are going outside more than once. Your contact informationElementary school students may still be in the process of memorizing your contact information. While your students teacher has this information, keeping it on an index card in your childs backpack can make him or her feel a little more secure. It is also extremely useful in emergency situations. [RELATED: How Parents Can Help with Elementary Homework Challenges] Middle school backpack essentials USB driveIn middle school, students will start using computers more and more frequently. They may also be required to do homework on their computer at home. Its easy for students to carry around their work on a USB drive. Make sure your student has one in his or her backpack. CalculatorMiddle school students will be doing more complex math and will thus need a good calculator. Check with your students teacher to see what kind he or she recommends. it could be a scientific calculator, graphing calculator, or both. Day plannerA day planner is a helpful tool for middle school students. Buy a planner with large spaces for each day so he or she has enough space to record the days homework with any notes. [RELATED: 4 Ways Parents Can Help Middle School Students Succeed] High school backpack essentials HighlightersHighlighters are often helpful to high school students, who do more reading than younger students. Learning how to highlight and read for important information is an essential skill high school students need for college. USB driveLike middle school students, high school students also need a USB drive to transfer their homework and assignments between multiple computers. Day plannerAlso like middle school students, high schoolers benefit from having a day planner. It can be used to record assignments, test dates, project deadlines, practices, meetings, events, etc. BindersBinders can help keep high school students organized for each class. Help your student label his or her binders, which they can take out of their locker as needed before each class. Be sure your student also has plenty of loose-leaf paper and binder dividers to stay even more organized.

English, Creative writing and SAT tutor in London

English, Creative writing and SAT tutor in London This week we would like to introduce Erica G, an English, Creative Writing and American SAT private tutor. She is originally from California, but is now a tutor living in London.  Erica is passionate about teaching writing and critical thinking skills through literature, and believes learning these skills can see individuals through much of their academic and practical challenges.   So let’s find out a little more about her… Erica, why do you love tutoring? I enjoy passing on knowledge in a subject that I love as well as building a child’s confidence in their own abilities. Often struggling children have the ability, they just need to believe in themselves. I love being able to instil that belief in a child by maximising their skills so they can reach their full potential. Who inspired you in education? My 8th grade English teacher and two of my lecturers at university where I studied writing and literature. They inspired me because they stood up for the right to education. They were strong teachers and taught me to think for myself in an original way and to believe that I could achieve great things. What else do you get up to besides tutoring? Well, I’m currently a PhD student so I spend a lot of my time doing my research for that. My research is in love and romance in LGBT young adult novels. I’m also an avid textile crafter so I enjoy quilting, knitting and doing some cross-stitch. I just love anything where I can express myself creatively. If you had a super power what would it be? If I could read while I sleep and remember everything in the morning that would be amazing. Then I would have a whole library of books stored in my head. What advice would you give to a parent on how to find a tutor? I would recommend first to find someone who is a specialist in the subject the child needs support with and then to find a tutor who can really help children believe in themselves. A personal tutor needs to be able to work alongside a student and act as coach as well as a tutor. Want to meet Erica?  See below to view her short video: Subjects taught by Erica English- Degree, IB, A-Level, GCSE, 11+, Primary, AS Basic IT Skills Blogging Creative Writing Internet Keyboard Microsoft Office Microsoft Powerpoint Microsoft Word SAT Twitter If you or your child needs help with any of the above then please click here to visit Erica’s profile page and book a lesson.

False Friends Spanish and English False Cognates

False Friends Spanish and English False Cognates One of the more difficult things that many Spanish speakers have while learning English is that there are many words that look and sound similar but have different meanings. We call these false friends or amigos malos. Learning English can be tough from the pronunciation to the grammar but false friends are not that difficult to memorize so that you dont make a mistake. The funniest example is: embarrassed in English sounds similar to embarazada in Spanish. If you tell someone in South America that you are embarrassed they will probably congratulate you and ask when you are due to have your baby. On the other hand if you tell someone that you are embarazada in the US or Canada they will probably ask why and ask if you are uncomfortable because embarrassed in English means that you feel awkward, dumb, self conscious, (verguenza).So below are a list of False friends that are commonly used incorrectly:Actual-means real NOT currentExample: The actual cost of the purse was much lower than the price tag.Particular-means special NOT privateYou can not discriminate against a particular group of people.Familiar-well known NOT relativeIm very familiar with the NorthWestern part of the United States, Ive lived there for many years.Casual-relaxed NOT by chanceThe restaurant does not require formal clothing, casual clothes are fine.Casualty-victim NOT by chanceThe war had many casualties.Soap-to wash your hands NOT to eat with a spoon like soupWe need dish soap for washing the dishes.Jam-is sweet and sometimes made from strawberries NOT ham which comes from cured pig meatMy favorite jam is raspberry.Compromise-an agreement or settlement NOT being engagedMy children are learning to compromise with each other by sharing and working out disagreements.Support-to give assistance NOT unbearable (unsopportable-doesnt exist)I gave her all the support she needed when her mother passed away.Molest-is generally used for sexual abuse or hurting someone in a sexual manner NOT to bother someone.Henry Weinstein the hollywood producers is accused of molesting several young actresses.Here Are The Best Tips For English Fluency:When you want to say: all the day/all the year change it to the whole day or the entire year.I was at the doctors office for the whole day!When you say take decisions you should say make decisions.I need to make a decision about her birthday gift.Remember breakfast/lunch/dinner are not verbs so you must say have or eat breakfast/lunch/dinner.What time do you normally eat breakfast? We eat lunch around noon. In Argentina they have dinner at 10PM!We talk in third person a lot for example: When at a restaurant and they ask how many people for the table you should say: There are four NOT we are four.There are five of us 4 adults and one child.We talk in third person on the phone: We say this is Teauna not I am Teauna.Hello! This is Teauna speaking, can I help you?
