Hi, I am planning to write the GMAT. It has been over 1.5 years since I last wrote it. I had then got a score of around 615. I want to improve my score, but not sure on how to start and scared if it doesn't go the way I want it. I will need advice from the group on what I should or how I should start. I don't mind studying with people who are also in the same boat as me.
