Hi Guys,

Have the GMAT in a weeks time and struggling with some Permutation Combination problems. Can anyone suggest a good online page to brush up on the knowledge and practice some problems?

Thanks

I'm somewhat biased, but our Counting Module (https://www.gmatprepnow.com/module/gmat-counting) covers everything you need to know for the GMAT.

Also, you might want to read my latest article for BTG, "Combinations and non-Combinations": https://www.beatthegmat.com/mba/2013/07/ ... ons-part-i

Cheers,
Brent
