GMAT Strategy

I just decided to take the gmat and signed up for a date in 3 weeks. I bought a book and will start reading it today.

Before studying, I took the kaplan practice test and got a 670, and the mba.com practice test and got a 750. Does anyone have any idea how accurate these are? I definitely need above 700, but I don't really believe that I got a 750 without studying?

I only have 3 weeks so I would love to have an idea of how hard I have to study...

Thank you for any advice!!!

Congrats on the good score! The practice tests you get from signing up the exam are indeed the very best, most accurate exams out there. I bet you'd be surprised at how many people do well with little or no preparation. They go to Wharton and Stanford and work for hedge funds .

For someone coming in cold, the "low hanging" fruit of improvements are usually the benefits that come from being more familiar with DS and some number properties. I'd continue to practice rather than read a book and you'll do great.
