Hi stigman17,
With a Q39, you would have made a number of little mistakes throughout the Quant section and you would have missed out on LOTS of 'strategy-based' points. At that level, it's possible that you need to work on your general math 'knowledge', but it's also possible that you know most of the math rules/formulas just fine - and it's just your organization and 'precision' that needs work. As such, I'd like to know a little more about your last practice CAT (and the more exact you can be with your answers, the better):
After reviewing the Quant section, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
Thankfully, the GMAT is a consistent, predictable Test, so you CAN train to score at a higher level.
GMAT assassins aren't born, they're made,
