This doesn't mean I'm going to do it. It means I'm thinking about it, and will make up my mind within the next two weeks. Or maybe I'll continue on my current track, take some course 10 classes, and go get a master's in course 10. I don't know.
It's also kind of late to be switching. Especially to, you know, the major with the longest prereq chains in the institute.
Any comments? I've been considering course 10 basically since I got to MIT - it's basically been a battle between it and 12.
