<p>Just wondering... why does one have to make a 5 on the AP Physics C test to receive credit for the class at UIUC? I mean, it was a pretty hard test. I'm surprised (maybe) that UIUC doesn't accept 4s for credit.</p>
<p>The physics department probably set the requirement to a 5 because you technically get credit for an upper level physics course which is probably more thorough and more difficult than the AP Physics C test.</p>
<p>AP tests are usually used to pass out of lower 100 level classes, but if they're being used to pass out of courses beyond the 100 level, then you generally have to do very well to get credit. </p>
<p>If you want a more credible answer, you should ask an adviser in the physics department.</p>
<p>A year or two ago, they gave Physics C credit for 4's, but they made the policy change because they felt those students weren't adequately prepared for the next physics class in the sequence.</p>
<p>Another factor probably lies in the massive curving of the Physics C test. Since to get a 5, less than 50% is required, perhaps anything lower would not show mastery of the subject like 4's on some other tests may show.</p>
<p>What they found in the past is that many of those who got 4's and skipped to the next level physics course were getting C's or worse in that next level course. It is the same reason that they are now no longer going to give credit for a 3 AP score in Calculus.</p>
<p>Yeah, my freshman roommate got 4's on both Physics C exams and got a C+ in the third physics class (Physics 113 + 114).</p>
<p>A lot of physics programs don't cover rotational kinetics or simple harmonic motion or stuff at the end of the year.</p>
