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. Verbal Problems Timing strategy
20 problems --> 35 minutes - skip critical reasoning questions early on (strengthen/weaken) - Skip combinations and permutations; or - absolute values with inequalities
Two independent sentences
To (Bring new info; Avoid weak wording) - Strengthen - Weaken - Evaluate
Assumptions - Conclusions

2. whether or not
Go straight for fractions
Proven wrong
Redundant - should just be whether
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!

3. 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

To (Bring new info; Avoid weak wording) - Strengthen - Weaken - Evaluate
Proven wrong
