GMAT Crash Course: All In One - 2

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. n(n+1)(n+2)
3 consecutive integers are even and divisible by 3
Almost always wrong
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
Joe or his friends are going. --> the verb correlates to the subject it is closed to when 'or' is used.

2. Like
Cannot introduce examples -- such as must be used instead
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.
Draw a diagram. The first thing you should do with any geometry problem that does not have a diagram is to sketch it out scratch booklet. And when you draw the diagram - try to brought scale that way be in a position to estimate.

(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

13. Reporting that one of ___ many problems had been the recent extended sales slump in women's apparel - the seven-store retailer said it would start a three-month liquidation sale in all of its torso.

y is 2 more than a multiple of 3
We are in the 'To category.' So - we bring something to the argument. It will not break the premises. For example - Mary: That guy is a newspaper reporter...; Joe: No! That guy wears a cape! Therefore - it is superman. We focus on explaining!
