Hey Rajat,
Just took a look at your test (kind of a fun thing to do over my first cup of coffee!) looking for some obvious areas for improvement, and found a couple things:
1) On the quant section, I counted TEN incorrect problems on which you spent less than a minute...but you had almost 20 full minutes remaining at the end of the section. So for one, SLOW DOWN. And secondly (and more instructively), go back and check for where you made silly mistakes and take note of what kinds of problems those were. It looks like you'll have plenty of time, so figure out where you want to give yourself a deep breath, a double check (did you set it up incorrectly because you were rushing? Did you need to go back and double check your work at the end?), and a little bit of patience so that you don't give away points that should be really easy for you.
2) On the verbal side, your greatest number of missed was on Reading Comp *but* the "easiest" questions you missed were all Critical Reasoning. So I'd suggest attacking Critical Reasoning first (you might want to check out this Youtube playlist as a starting point:
https://www.youtube.com/watch?v=aVtBEVjBNd8&list=PL8IRdvEjAM5LsQWiqVpmsQKz0wBKzbDdr) so that you raise your "floor" and minimize the number of below-average difficulty problems you miss as a start. Then of course you'll want to address Reading Comp as well, but for now I think you'll get a higher ROI by attacking CR.
3) One other thing that stood out - you weren't really in danger of running out of time on either section (verbal you took 1:12 but that still leaves you 3 minutes) but on both sections your last few questions were really rushed. You may want to try studying in longer sessions to build up that stamina...seems like you're kind of "giving up" toward the end and phoning in the last few questions...those ought to be easy points to pick back up since you do have the time.
I hope that helps!
