A lot of people say you should allow at least 3 months of study time; more if you can't commit a lot of that time to studying. Anything you can get your hands on can be potentially helpful depending on your perceptions of the GRE. As you go through the material you should be reminding yourself about the ways you might get caught up. Keep in mind patterns and different ways you can approach a problem. The GRE doesn't require you to have a broad understanding of archaic words; rather you should be able to use the context of the sentences to help you eliminate words that don't fit. The quantitative section is the same, the GRE often uses patterns and finding these patterns will help you solve the mathematical questions
That's neat, but I'm curious. Are the bullets based on how they should follow chronologically in the personal statement or just a general inclusion of these?
