I took the GMAT in Mar, and scored 640 (Q39,V48). I've planned for a retake in mid May.
I'm wandering if anyone can give me some tips on how to improve my quant?
I've been through the Manhattan GMAT guides
and did all the OG12
questions, although I still feel that my concepts are rusty and under time pressure can't think clearly on the problems.
Any help would be very much appreciated
