PR scoring chart for Bio accurate?

<p>how accurate are the scoring charts in the PR book for SAT 2 Bio?</p>

<p>it says that 78-89 is an 800...i find that quite hard to believe.</p>

<p>i got a 73 for my practice test. can anyone tell me what score i might get on the actual test? i don't really trust the table in the book...
thanks!</p>

<p>Meh. Take the CB one.</p>

<p>what would 19 wrong be based on the CB scoring chart?</p>

<p>where is the CB scoring chart? is it in the big official SAT subjects book or can it be found online?</p>
