If you’re going to do a great job on the GMAT, then you’ve got to know how to Test Cases. This strategy will help you on countless quant problems.
This technique is especially useful for Data Sufficiency problems, but you can also use it on some Problem Solving problems, like the GMATPrep® problem below. Give yourself about 2 minutes. Go!
* “For which of the following functions f is f(x) = f(1 – x) for all x?
|(A)||f(x) = 1 – x|
|(B)||f(x) = 1 – x2|
|(C)||f(x) = x2 – (1 – x)2|
|(D)||f(x) = x2(1 – x)2|
|(E)||f(x) = x / (1 – x)”|
Testing Cases is mostly what it sounds like: you will test various possible scenarios in order to narrow down the answer choices until you get to the one right answer. What’s the common characteristic that signals you can use this technique on problem solving?
The most common language will be something like “Which of the following must be true?” (or “could be true”).
The above problem doesn’t have that language, but it does have a variation: you need to find the answer choice for which the given equation is true “for all x,” which is the equivalent of asking for which answer choice the given equation is always, or must be, true.
Manhattan Prep offers instructors flexible hours and great pay ($100/hour for all teaching and $116/hour for all tutoring). As a Manhattan Prep instructor, you will have autonomy in the classroom, but you will also be joining an incredibly talented and diverse network of people. We support our instructors by providing students, space, training, and an array of curricular resources.
Our regular instructor audition process, which consists of a series of videos and mini lessons, usually takes weeks, even months, to complete. Through this process we winnow an applicant pool of hundreds down to a few people each year.
We are offering a one-day event on April 12th for teachers interested in working with us. Candidates who attend will receive a decision that day. The event will take place at our company headquarters at 138 West 25th St., 7th Floor, in Manhattan, New York City. It is open to candidates who live in the tri-state area, have taught before, and are experts in the GMAT, LSAT, or GRE.
The day will include several rounds of lessons, as well as other activities. Each round will be pass / fail. The day will begin at 10:30 am. It may last as late as 5:30 pm for those who make it through the final round. Candidates will need to prepare lessons for some rounds; we will send more detailed instructions to candidates when they sign up for the event.
To register, please email Yanilda at firstname.lastname@example.org by Wednesday, April 12. Please include in your email a resume including your teaching experience and a score report.

U.S. News & World Report today released the 2016 Best Graduate School rankings. As our friends at mbaMission have reminded us, all rankings should be approached with skepticism. “Fit” (be it academic, personal, or professional) is a far more important factor when choosing a school.
That said, here’s how the top 15 American business schools stack up this round:
1. Stanford University
2. Harvard University
3. University of Pennsylvania (Wharton)
4. University of Chicago (Booth)
5. Massachusetts Institute of Technology (Sloan)
6. Northwestern University (Kellogg)
7. University of California, Berkeley (Haas)
8. Columbia University
9. Dartmouth College (Tuck)
10. University of Virginia (Darden)
11. New York University (Stern)
11. University of Michigan, Ann Arbor (Ross)
13. Duke University (Fuqua)
13. Yale University
15. University of California, Los Angeles (Anderson)

So you’ve taken the test and you aren’t entirely happy with your score. How do you decide whether to re-take the GMAT?
It might be the case that your score is close to what you wanted, but not quite all the way there. Alternatively, you may be trying to decide whether to stick with the GMAT or switch to the GRE (and, if so, I recommend you follow that link).
If you already know that you do want to stick with the GMAT, read on. Read more
