Try these problems

Those problems are quite tough. Try to utilize them and review those problems.

Thx so much!

Well, I'll offer a somewhat differing opinion. Working out a bunch of random difficult problems is certainly one option. But, I'd start analyzing your previous CAT results and figure out for yourself why are you missing the questions you're missing. Is it because there are some basic concepts you haven't mastered. Is it because you're making careless mistakes. Is there a theme - i.e. are you consistently missing a certain type of question. Basically try to figure out WHERE you are coming up short and then concentrate on improving in those areas. Remember, "tough" GMAT quant questions are not tough because they require advanced math or excessively cumbersome solutions. They're tough because they combine multiple basic concepts. So the way I see it, your job is to (a) master the basic concepts required for the GMAT and (b) practice applying these concepts in a variety of ways. So, improving CAT scores seems to me to be an exercise in self-discovery.
