Stancey,
Just to give you additional information, today I took more tests.
MGMAT 3- only quant q49 (90%)........26/37
MGMAT 4- only quant q41 (93%)........24/37 .this one was incredible.........how could I have a percnetile 93% and stay with 41?
MGMAT 5- 750 q51 v41
q- 28 correct /37 (19 700-800 and 18 600-700 level).
v- 26/41 (but 33 were 700-800 level)
Just to compare, last week i got 760 in GMATPrep1 q50 (31/37) v42 (34/41)
After i had finished MGMAT5, i knew thai i had got >700, but not 750. MGMAT5 is more difficult than Gmatprep1.
