Subject : gmat

Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

1. How to do assumption problems?
(1) Must be supported by premise (2) Never supported by anything (3) If you have two sentences - put therefore in between and see if it makes sense
Avoid extremes
(1) Read question first (2) Read for structure and look for gaps (3) Work from wrong to right (4) Negation test: If you negate the argument will fall apart - Answer choices that bring in new information are wrong - Look for reverse causation
Add the exponents to determine the answer.

2. When choosing numbers... don't choose 0 -1 or any number in the numerator or denominator
