Hi
I was wondering if when you study (not during the test) is a good strategy rather than to look at the two options to answer the question, to write down what do you think you need to answer the problem.
Would this take to much of my time?

It's a good idea to think about this, but you obviously don't want to spend too much time brainstorming - really, you should just always have those thoughts in the back of your head as you do a problem - as you're reading something, you should be thinking, "What does this really mean?"

You should also look at the information given in the question stem and see if you can rearrange or rephrase the information in a more useful way (before you even look at the answer choices). This exercise often then tells you what you need to know in order to solve the problem. For example, if they ask me something about (n^2 - n) where n is an integer, I can rearrange to n(n-1), which is two consecutive integers (n-1, n). That's a very useful piece of information.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
