Hi
Could some one please tell me how many questions related to P and C do appear in GMAt ?
I am planning to leave this topic untouched for my preperation. do you think i can still do well in the maths section without this?

you can probably still do alright...

first, it depends on score you are shooting for. if 650 or better, you cannot leave P and C alone.

second, remember its CAT.You get rewarded(categorized in higher gmat percentile) for problems you get that no one else gets. Also, you get rewarded with harder problems as you nail all the problems. So if you are doing well, P and C will be bound to show up.

third, the GMAT is comprehensive, which means each problems is a combination of problems. They are testing multiple things at once, not just one. So a P and C problem, unbundled is actually a ratio problem, or probability problems. So good preparation for a good score means you have done some work on P and C.

Good luck!

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
