Subnetting in CCNA exam

Do you need to know how to subnet and apply VLSM to class B networks as well as C's? Or is it better to concentrate on Class C's for the CCNA exam.

Cheers to anyone who responds.

ALL.. There's little point in only knowing Cs and vlsm.

Once you figure out Cs, it's not much more to figure out the rest. Have a search for this topic in this forum and you will find some very good articles which explain subnetting very well.
