<p>I am a Canadian, and have little experience with the AP system. I'm taking quite high level courses, which I believe are at the AP level if not higher. I'm applying to American Universities and will probably be taking some AP tests, like the Physics B or C, the Calc BC, maybe Chem. The problem is, I don't quite get the scoring system. I looked at some of the questions on the collegeboard site, and I can do them, but i doubt i would ace them, I usually make a few dumb mistakes. What percentage does a 5 equal? A 4? A 3? Even purely speculative ideas would be helpful.</p>
<p>there is a grading curve for each test. these 1 -5 scores are yours relative to your peers. i think college board has the chart for the score you get and what percentile you are in for each test.</p>
<p>The Calc BC and (both) Physics C curves are crazy. If I remember correctly, my instructors told me that one of them a 68+% was a 5 and in the other a 71+% was a 5. A 50 often gets you a 4.</p>
<p>Most other tests are closer to 75% for a 5, but this still very attainable.</p>
<p>I didn't take chem, so I don't know the specific score ranges for that.</p>
<p>I'm pretty sure chem is around 70+% for a 5 (at least, that's what our teacher told us last year). The test changed in 2007 though, so I'm guessing it might be around 65+%.</p>
