Okay, after finally reviewing my performance, problem by problem. I can conclude that I am an idiot and that I made about 1000 stupid mistakes.
However, you guys should know that kaplan makes errors on tests and their answers. I found 2 errors in answers going over this form. I have found more before in other forms.
(these are blatant errors like using Power = Resistance / Vsquared instead of Power = Vsquared / Resistance to get their answer). its pretty unacceptable if you ask me.
