Replying to College classes in HS?

i thinking about taking some college courses this year at the local community college (we call it running start, i dont know what you call it) and i was wondering what they are like? im thinking about maybe tai chi, intro to paralegal, sociology, some english, a course about better understanding college textbooks, weightlifting, medical terminology, or macro economics. any ideas on what they would be like? anyone done this? did you like it?
