I see gaps in exponents and roots, most of geometry, Combinatorics (if you get it in the first 1.5 mins, you are done, else you are wasting time), rate and work. Give 2-3 days to each topic. I have written posts on all of them; check them out here:

If you are missing 750 level questions of a topic, you shouldn't worry about it. All you need to do is get all the 700 level questions. If you ensure that you get up to 700 level questions of all topics, you should see a good improvement in your Quant score.
