Hello:
I have taken kaplen in my preparatoin for dental school, my diognostic test sucked, but at the end of the term, the result was great. Just do what you the book tell you to do, do the practice tests, library and you will do fine. By the way I am from Portland too and I got accepted into dental school in the eastern state let me know if you have any more question.
I wish you the best
Sincerely
Doctor2Be
