I potentially have four, but I'm hoping I'll only need to take two. I'll know tomorrow. I really need to study up hard for my Cal 3 one on Friday so I can pull out on A. Programming's the other definite but it should be cake like everything else in the class. Astronomy is optional but would be easy if I really had to take it to get the A. Digital would be a huge pain in my butt if I needed to take it, so I'm only going to if I need it to get or hold a B or if an A is reasonable.
