Calc BC Scoring- I'm so confused!

<p>I have the Princeton Review book and it doesn't seem to explain scoring, which seems very odd, and that leaves me with some unanswered questions:
How much is each free response question worth?
How do I compute my raw score?
What is a good estimate of a minimum raw score for a 5?
thanks!</p>

<p>fr is typical 54, mc is 54, 108 total, need about a 65 to get a 5</p>
