Ah. I started to do that, just didn't pick up the pattern correctly. Thanks for the peace of mind, it's much appreciated.

Took the GRE today and one question on the Quant section I'm still struggling to figure out, wondered if any geniuses here could explain this one to me. 3 to the 82nd power divided by 5 leaves what remainder? It was a multiple choice, not a quant comp, so somehow you were expected to deduce this answer. For the life of me, I can't figure it out. I've since written a computer program to output all the remainders from 3 to the 0 to 3 to the 82nd power but I can't see any pattern here, nor can I brainstorm any way to simplify this question. Any insights would at least give me peace of mind, although not change my score. Thanks for your help.
