How does this Raw score system work - Sat BIO?

<p>Hey all,</p>

<p>Used this <a href="http://www.sparknotes.com/testprep/books/sat2/biology/chapter2section6.rhtml"&gt;http://www.sparknotes.com/testprep/books/sat2/biology/chapter2section6.rhtml&lt;/a> as a resource to try and predict my SAT II bio today. I skipped 9 (couldn't make educated guesses) which would put me at 71/80 on the raw - 740. And assuming lets say I get 4 more wrong of the 71/80 that would subtract 1/4 of a point each so it'd put me to 70/80 raw which is still 740? Is that how it actually works? That's sort of pretty easy then. Someone get back to me thanks!</p>
