play nicely. Its called tolerance and understanding. Sure one freak may (ooops, did I say freak?) feel that prepping for an exam for months is inappropriate, but there are plenty that are cruel and heartless and lack even basic interaction skills to get information from a bass. But whatever!!
Everyone be happy and play nicely!
And speaking from experience, if you feel that that is what you need to do, then do it. If you feel the need to do Kaplan or TPR to make a qualifying score (don't let anyone tell you there isn't one because virtually all schools have a cutoff) then do that as well.
Point is, you do what works for you, not what some ace with a 30 tells you.
