AP Psych self study?

<p>If I signed up to take the test and just the Princeton Review, what would be my chances of scoring a 5 and receiving college credit? Last year, I took AP Bio and got an A in the class and feel very confident I got a 5. I heard the tests are alike in structure and wanted to know if doing well in Bio would give insight on how I would do on the psych AP exam. How would taking the exam without the class look to colleges? I will probably already be accepted into colleges by time AP exam week comes, so is their a way to show them I am taking an AP exam for a class I am not taking? Thanks</p>
