Plzzz also explain ur approach & wat u all did in preparin 4 quant section !!!Plzzz suggest some materials also 2 raise quant upto a fair level !!!
@arunrajput1007 i remember the second set of books which time gives have very good standard and very wide variety questions.
Later try to do the sectional tests that are put up on time SHP. You will experience wide variety of qns there and also helps in improving the speed. Do remember to know the correct procedure and answers to all the qns u answer instead of just attempting a number of tests
I did this the same last year(a bit this year too) and it worked for me perfectly.
