What score do I have on this AP Calc AB practice Exam?

[ilovephysics0]

I've been self studying AP Calc AB over this past month, and I just took a practice AP Exam. It is the first AP Calc AB test in the princeton review's ap calc book 2010 edition. I got 31/45 on the MC and roughly 50% of the FRQ's correct. Could someone estimate what I got between 1-5? Thanks!

I would guess those scores would make about a 4 on the exam based on what I remember from taking the class a few years ago. I remember in the beginning of that book they tell you the rough percentages you need to score what so you should consult that.
