Avi,

You do not say why you are taking precalculus. If you are taking the exam to meet the Excelsior business requirment for precalculus, be advised that the College Algebra CLEP counts as precalculus work. But perhaps you need this exam for another reason or different institution.

My understanding is that the precalculus exam conists of more functions, logarithms, and trig than the college algebra CLEP.
