20 hours semesters?! I hope whoever tries that doesn't have classes like I had.

I started out as a music major, where it is remarkably hard to do 12 hours if you focus on performance classes. For those that think it's an easy major, it's not. Many classes are 1 credit hour, but meet 4-5 times a day. Then there are the 0 credit hour classes that are still mandatory to take. I didn't know better, focused too much on music classes, and I had to quit, even though that was pretty much all I did.

When I did go back to college, I changed my major to something in the liberal arts and sciences college. Despite that, 12 hours was more than enough. 15 credit hours was a necessary evil sometimes. I did 16 credit hours once, but that was hell.

Now, I am not a bad student by any means. I'm a very fast learner and I do know how to budget time. But I've seen how hard it can be to take too many classes at once. I had friends that took too many and as a result, they often ruined their GPA and lost their scholarships.

So...

Take your time with college. Enjoy it. Work part time if you absolutely must. But don't take a load you can't handle because even if you make it through, you may well come to hate the field you're studying.
