GMAT Strategy
2) Learn the strategies from Princeton Review and Kaplan. But use what you are comfortable with.
3) Don't go Test Crazy. You will get burnt-out and you will pay less attention to details when you take the actual test. Take one test a week or so.
4) Use the 10th edition like it was the bible! Start from the back of each section, those are newer CAT problems.
5) Do problem sets in 1.5 hour blocks. Keep track of how many you do in a certain amount of time and make sure you pace yourself.
6) Learn from your mistakes! More important than getting the answers right - and feeling overconfident - is understanding why you got the question wrong.
7) Relax the days leading up to the test. Don't cram.
