Thanks for the reply. but post reading mgmat guides
the basic concepts of most commerce grads couldn't be sorted out yet. may be its coz of a bit low logical usage as compared to engineers. I am not giving an excuse to score low on gmat because of non-math grads.. but I want to eradicate that eXcuse and boost confidence amongst all non math gmat takers. after a long research I came out with three books for non maths grads for scoring 48+ in gmat maths.. namely kaplan
gmat math workboob, kaplan
math foundation and total gmat math
. its but obvious after any of these books one has to go for mgmat,gmatclub tets, and og and gmat prep mocks.
reviews about these three booms awaited keeping in mind that this i first step to get good concepts clarity.
