I completed the OG and averaged around 80% correct for all the quantitative questions. I took the first GMATPrep test today and ending up just giving up because of how difficult it seemed. The questions seemed nothing like the OG questions, minus maybe one or two. Am I missing something or is the OG just a compilation of the easiest questions GMAC could find?
EDIT: I also noticed this the first time I took the GMAT (got a 580, despite months of studying).
If my post helped you, please consider giving me kudos.
