Nah, The Solar System is a senior level course. It is not my area of interest in astronomy, but the professor is fantastic, so I couldn't pass it up. Course description: Formation and evolution of the Solar System. Planetary surfaces, interiors, atmospheres, and magnetospheres. Asteroids, comets, planetary satellites, and ring systems. Emphasis on using basic physics to understand observed properties of the Solar System. Intended for students majoring in the physical sciences.
I had a better schedule when I took high energy astrophysics, though.
And differential geometry is a senior level course, but I got the feeling that it is not going to be proof based. Over the past two years, there are 70% A's. Either there has been a lot of brilliant students, or that is kind of messed up.
