My sophomore year, AP World History was a senior elective, and I was really interested in taking it. My school switched to AP World from AP Euro as the AP sophomore history class this year. Now that I'm a senior, I managed to transfer into a very full class, but my teacher, who I had for AP Euro, asked me to be some sort of psuedo-TA-AP student, so it could free up a space for a sophomore. I would help him grade papers, but take tests and notes, and do homework, just like the rest of the class. My schedule would say Teaching Assistant, instead of AP World History, even though I'm doing the AP work. How could I communicate to colleges that I'm not slacking off with a filler class, and that I'm actually doing more work than normal?
