Yeah, I agree. Bio classes are harder than sociology. I've taken a lot of courses in university because I switched majors like crazy. Here's my ranking from hardest to easiest:

1.) Biology w/killer labs
2.) Psychology w/bio
3.) Economics, statistics
4.) English, Political Science
5.) History, sociology
6.) Philosophy (EASIER THAN GRADE 9, I could write a term paper about my eyebrows one hour before class and get 80%)
7.) Religion (ZZzzzzz..........)
