heck, all of that stuff is fun!
The only downside is that you'll spend so little time on each subject that you won't get much out of it. Of course, it could whet your interest enough to go seek out a full course on the interesting bits. I've had a full semester class on filters, both active and passive. Amazing stuff.
A good class on semiconductor physics is pretty amazing stuff too, but can be intense. Depends on whether the physics or EE dept teaches it. I definitely recommend getting it from the EE guys. Much more applicable.
A good chapter on semiconductors might be enough for most folks though. It's important to understand what's going on inside, if only to understand why all the non-ideal behavior happens.
have fun with the class! I hope you have some labs to go with it.
