It is possible but it depends on a few things:
1) How much studying you have put in (the further you are in, the harder it gets to improve)
2) What materials you have used
3) How much time you have (quality time, not 10 PM after a bar type of thing)
4) How much effort you can put in
So... if you have just 33 days, I would grab the Kaplan Premier book and run with that (as I don't think you have enough time to cover
MGMAT or Veritas Prep books). If you can go through the Kaplan Premier, I would grab Kaplan Math workbook and Kaplan Verbal workbook too (and do whichever you struggle the most with quant/verbal).
Finally, if you can pick up a copy of the
MGMAT Roadmap - I highly recommend it to anyone. It is a book for after the bar

Good luck!
