I am. I was ill just after Easter and so missed a few days, but then on the night before going back in I just thought about how much work I'd covered in those few days in comparison to the stupid posters and mindmaps (literally all I do) I was doing at college, and thought, 'Why not?'
Honestly, I've taught myself so much just learning it on my own. My college has been on my back, predicting me low grades, telling me I'm going to fail my AS Levels, etc, but I genuinely don't think that's the case. In the time I would have spent drawing posters to make the classroom look pretty, or going to the library to find there's no free computers (my teacher does this all the time in History; every lesson we get sent off to the library to do some research on the computers, only to find there's none spare), I've been doing past papers, looking at the specifications and AOs and writing out notes - exactly what I wasn't doing at college. This could all backfire miserably, but I think I'm more prepared for my exams than if I'd gone into lectures and done absolute crap.
(I should add that my college is rubbish and barely anyone gets good marks; on the rare occasion that someone gets a B, the teachers go wild with excitement. If you have good lecturers or go to a good college, you could always go in for a few days before the exams, because that's usually when they start to get a little worried and go over the exam spec. Other than that though, if you're motivated and prefer to work alone, I can't recommend skipping college enough.)
