I too tok 1
MGMAT test 3 weeks before the test and got 660 or so. I remember getting 49 in Quant, eventhough I made only 4 mistakes. Either thier Verbal was awful or I was
IMO, the best resources for each type of question are:
CRs - Just focus on GMATPrep and CR1000 (only weaken/strengthen/assumption/paradox/argument evaluation..)
RCs - again OG+GMATPrep+a few RC1000 (don't pick the History+Law passages. On GMAT you are more likely to see 1 or 2 business passages than Justice System/Law passages)
SCs - OG +
MGMAT SC Book + SC1000
Again this advice is from someone who could score 80% in Verbal.. so there is my disclaimer
Good luck!
