Can anyone share their strategy on how to review Practice GMAT CATs (i.e. how much time to spend reviewing them, how to track your weaknesses, etc?) and how to analyze one's results. I've read that some people use answer grids to analyze results in quizzes and problem sets but how can this practice be applied to GMAT Practice CATs? Also, when taking GMAT Practice CATs do people typically set up some type on answer grid on their scratch paper to keep track of choices that they have eliminated?
