for practice i will recom you to do questions category wise initially and subsequently do all kind of questions altogeather ..for e.g
If u have problem with parallelism, u may read relevant SC chapter of MGMAT SC
guide, do the prac given at the end of the chapter, do the relevant OG prob(may be both og 12
n verbal) and do tons of prac specifically of Parallelism on this forum....rinse n repeat for other chapters also...once you've gained adequate proficiency...do bunch of problems of all categories.. then check if u have any problem with any particular segment out of all...hopefully u should not....however if in case u have then go over that chapter again and kill the ISSUE BY UNDERSTANDING THE CONCEPT & INGRAIN IT IN UR MIND BY DOING ADEQUATE NUMBER OF PROBS ON THAT SUBJECT....hope it helps...all d best..
Fire the final bullet only when you are constantly hitting the Bull's eye, till then KEEP PRACTICING.
