You ask a great question. Review definitely is a significant component of successful GMAT prep. As you know by now, there is a ton of information that must be mastered for the GMAT, so if you don’t review, you likely will forget key concepts and principles, right? I think it’s great that you’ve created flash cards and are regularly reviewing them as you progress through your studies. In addition to flash cards and notes review, doing mixed problem sets of past topics is a good way to review old concepts and ensure that nothing has slipped through the cracks. We actually make a major point of having TTP students complete various review quizzes and tests (as you know very well) as they progress through our course.
So, keep up with hard work, my friend, and feel free to reach out to me directly with any further questions. Let’s do this!!
