GMAT Strategy

I am currently using MGMAT study materials and just began the Knewton online course. Currently, I am answering practice questions for each topic covered in the 50% range. I understant it is more important to review questions that I get wrong in order to learn from my mistakes. Any other suggestions on improving practice and learning this material? I am shooting for the 700 level come test day. Sometimes I feel like I need to go back and re-read all the subject material.

Thanks in advance for all your advice.

You should definitely take notes when you are learning. Maybe you already do, but many students who take advantage of online courses consider note-taking a waste of time. I think it is very useful because you can always come back in no time to every subject you have already covered and review the basics.
