...still feeling not enough...
i know Gmatclub test 's perfect...i think i'll buy it later...
could anyone recommend me another source of Quan test beside Gmat club test??
Try GMAT Focus quant diagnostic from mba.com. They are official questions (but very few questions for lot of money). I have not tried them but have heard good reviews from few people. Moreover the tests are adaptive. http://www.gmatfocus.com/
