I can't get any better in GMAT .. Please HELP

Hi khaledyosry,

Thanks for reaching out.
Could you please give a bit more information? This would make it easier to give you advice. Specifically:
1. Have you taken CATs before? If so, what were your scores? I need to know this to know more or less where you're at in terms of ability.
2. What is your target score? This is extremely important for determining a study plan - the amount of work necessary for a 650 and 750 are vastly different.
3. Have you built an error log for yourself? This is the most important part of self-improvement. When you study, you should not try to answer as many questions as possible but rather learn as you answer: What types of mistakes do you tend to make? What types of solution approaches work best for you?

If you like, check out our video on Introduction to PAL on our website here. There we explain the PAL system - 3 complementary and radically different approaches with which to solve different GMAT questions (our course specializes in adapting the right approach for each student). As different students have different strengths and weaknesses, you shouldn't expect that a 'one-size-fits-all' book will work for you. Instead, you must search for the specific approaches that make your life the easiest.
