Subject : gmat

Instructions:

Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can study here.

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?
z > x + y + 1 - x + y + z > 0 - x + y + 2z > x + y + 1 --> z > 1/2
(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

8. How to eliminate answers on geometry questions
Many geometry problems come complete with a diagram drawn to scale. Most people get so caught up in solving a geometry problem geometrically that they forget to look at the diagram to see whether the answer is reasonable. Simply using approximations
108 --> 2 -2 -3 -3 -3 12 --> 2 -2 -3 9 --> 3 -3 - Because you cannot be certain that the 12 and 9 share the 3.
