You ask about the GMAX Online course. Check out some of the lessons here in the review of the course and on You Tube. You will see how carefully and thoroughly we teach the concepts and strategies for all the different subjects.
You must be prepared, however, to study properly if you aim to raise your score seriously. They typical student studies for about 2 hours a day: one day to take a lesson, the next day to study it and do the homework.
After you have taken the midterm exam and seen your progress (we include 3 CAT GMATs with the course), you should be able to schedule your test. Be careful, however, not to schedule it too early. You want to have enough time to finish the course, do a thorough review, and take practice tests.
Good luck.
