Can someone let me know what is the best place to get a good grounding in P&C and build on top with some tough problems?

Does Kaplan/OG/PR cover it?
Thanks

Does Veritas offer a course or do they have books too?

they have a general course..

but as part of their course here.. they have a whole book on permutations and combinations and probability. real good.

veritas has good course materials.
sc,rc,cr is tough
math is tough too.
but their tutors are not good.
they have an ok phone and email support. each time you email them, it takes2-3 tries before you get an answer...

i am planning to sell mine in 1 month

Great post, the links are very helpful

Folks
There is a downloadable document at

However, this link seems to be dead. How can I get this document?

Also, I am eagerly looking for advice on the Permutations and Combinations section. Anything is welcome along with some training and some practice problems.

Thanks a ton.

If you REALLY want to dive into permutations and combinations, Veritas has a dedicated gmat book for it.

I personally think that permutations and combinations are grossly overrated. Most that I've encountered are not of supreme difficultly, and they are not common. I'd stick out my neck and say that you can still get a Q50 without much knowledge of it.
