<p>If you're just interested in getting physics out of the way and preparing for the MCAT, 8.01 or 8.01L would be absolutely fine. The MCAT almost certainly doesn't cover physics to the depth that 8.012 does.</p>
<p>For gigog, I think it's worth it to take the AP test -- then you can decide later this summer if you're interested in using the credit or not. If you're not interested in being a physics major, I don't see anything wrong with using 8.01 credit and moving on to 8.02.</p>
