<p>Damn really? I’m reading Apostol to self-learn for the AP Calculus BC test (well, mostly because I want to learn ‘for myself’ out of curiousity, but this is a nice ‘side-effect’). ^_^</p>
<p>My son’s school uses Spivak for their most advanced Calculus class. His teacher says they are one of the few high schools to do so.</p>
<p>^^ Certainly that is uncommon to use, yes. It’s very healthy, though, as it will give a taste of what the real stuff is like.</p>

<p>I asked in the SAT/ACT board about this, but for now here is what is found by a quick search of the College Board site: </p>
<p>Raw score (number correct minus 1/4 of number wrong, on 54 questions)
54 —> 800
50 —> 710-750</p>
<p><a href=“http://www.collegeboard.com/prod_downloads/highered/ra/sat/sat-raw-scaled.pdf[/url]”>College Board - SAT, AP, College Search and Admission Tools;
<p>For example, answering everything with 3 mistakes is a raw score of 50.25.</p>
