Last year (11th), my school put me in an AP course (bio) which I did not select, due to the ones I wanted being full.
I sort of had few options, because I could either stay and persist or drop it. I didn't want to drop because doing so would make me look lazy taking fewer classes than the norm, and all the other electives are full, so I decided to persist.
However, that was a bad idea, because the immense amount of work in that course led to my screwing up a lot of classes.
I don't have an available essay, because my third one was allotted to discussion of my interest in my major. Comments box, perhaps? =(
I am doing much better in comparison this year, but the semester hasn't ended yet so there are no final grades. There are already a couple of classes in which I'm pretty much guaranteed an A, though I of course can't state that. I wish I could note this somehow...
