<p>I just found out that the FR percent of total grade changed to 50%. You can check this out here: <a href="http://apcentral.collegeboard.com/apc/public/repository/ap07_freeresponse_direcs.pdf%5B/url%5D">http://apcentral.collegeboard.com/apc/public/repository/ap07_freeresponse_direcs.pdf</a>
Does this mean anything?</p>
<p>It was always 50%, wasn't it?</p>
<p>I thought that it was, but I don't know. Also, the links says that answers "algebraic or numeric" don't need to be simplified. What exactly does that mean? If I evaluate a definite integral and end up with 6 fractions or so, I can just leave them like they are?</p>
<p>yeah, you dont have to simplify at all on the FR. you can say "sin(pi/6) + tan (0) - sqrt3 + 5" If you simplify wrong, you lose a point, or more. When you are done doing calculus, you are done. This is not AP algebra. At least thats what they say.</p>
<p>Wow, that's awesome. It's usually during some stupid operation (i.e. adding fractions) that I make a mistake, so I feel like popping out a bottle of champagne right now. Hopefully I won't have to use an answer as a part of a later problem.</p>
