That's it! You're through! So.....


How did I do?

-----------------------------------------------------

0-10 --- Are you even in psychology?

11-20 --- Try reading the psych book first next time.

21-25 --- Doing better, you could use some more studying though.

26-30 --- Probably better than I could do.

31-35 --- You must have studied quite a bit.

36-40 --- You're in AP biology aren't you?
