I'm looking to fill in my free credits. I'm looking for nice 1-credit hour class, maybe a 2 if I'm really loving it.

the lower level military classes are fun and most are 1 hour. ive taken rifle marksmanship and im in wilderness surivial now.

Mining 151 or 003 are both one hour, they're pretty interesting and really easy. Unless you are a mining student and have already taken them.

The pyrotechnics class is 3 hours, but it's all on the weekends, and does involve pyrotechtnics. The final is a big fireworks show near KC.
