Hello,
I've been studying for about 11 weeks now, and I'm trying to get an accurate prediction of where my real gmat score will end up. I've taken 4 MGMAT CAT and the GMATPREP #1. The scores are never very close, despite being taken only a week or two apart.
MGMAT CAT #1 (11 weeks ago): 560
MGMAT CAT #2 (4 weeks ago): 530
GMATPREP #1 (3 weeks ago): 600
MGMAT CAT #3 (2 weeks ago): 640
MGMAT CAT #4 (yesterday): 690
I took CAT #1 untimed. CAT #2 was timed, but I was incredibly rushed for time in the quant section. I was basically guessing the last 10 questions.
CAT #3 and GMAT PREP #1 were timed, and I attribute the improvement to learning a timing strategy where I make an educated guess if I don't have a handle on the problem after 90 seconds.
CAT #4 was taken one week after GMAT PREP #1. I didn't study any new timing strategy. I really didn't learn a whole lot of new material, since the tests were only a week apart.
I've gone froma 530 to a 690 in 3 weeks, and that just doesn't make sense to me. My biggest worry is the verbal scoring, which is highly erratic. On my baseline, I scored in the 91st percentile. On the following 2 CATS, I scored in the 72nd percentile. On the most recent CAT, I scored in the 91st percentile again. Mind you, I haven't devoted any study time to the verbal section, since I scored so strongly on the baseline. Why is there a 19 percentile point difference between exams #2/3 and #1/4?
And finally, on my latest test, the overview said I scored a 42Q (70th percentile) and 40V (91st percentile). My OVERALL percentile rank was 91st percentile. How is this possible? If I scored 70th percentile quant and 91st percentile verbal, even a weighted average wouldn't put me at 91st percentile overall, unless verbal was weighted 100%. According to several charts I've looked at, a 42Q/40V score translates into a 660, not a 690. What is going on here?
