I'm seriously debating whether or not to take a prep course. I was going to apply to programs this winter, but I ended up scoring much lower on my actual GMAT exam than my diagnostic! I was going to cram with self-study for the next few weeks and take the test in January, but I'm thinking it may instead be better to study seriously for a few months. I want to achieve a score over 700.
I would love to hear feedback about study methods and prep courses, including what you have found to be most effective. I don't mind paying a few thousand for the prep course, but only if it's actually going to help me increase my score more than self-study would.
Thanks in advance!!
