I appreciate the feedback. I will definitely take this into consideration as I make my choice.
However, I feel like their are a lot of tricks and strategies I may be missing out on by essentially teaching myself. This is where the course would come in, to make my personal studying more effective. I do agree with you both that there are no quick fixes.
So far I have done the following for prep:
OG 11
GMAT Prep Software (excellent)
Princeton Review Online (the $99 one)
800 score practice tests (scoring algorithm is weird)
MGMAT practice tests (difficult quant section)
My practice test scores have ranged from 550 to 700 so I have no idea what to expect on the real test. I am mainly focusing on Quant, CR, and SC. Timing is also an issue for me.
If I do decide to go the course route, are there any particular companies you regard highly?
Thanks again
