The only downside I can think of is how much time it takes up. It is a relief to have my evenings back for winter break! I almost don't know what to do with all the spare time!
This upcoming semester I'm going to increase my credit load to 9 credits (from the 6 I did for my first one) and see how it feels. I'm being cautious, I don't want to over commit and then be stressed out by too much work and school and hate college! The extra class I'm taking I decided to take online though, I think it is the smartest decision. That way I will have more flexibility and not feel like ALL my evenings are taken up with school. Maybe I can even do some homework at work, during my downtime.
I will let you know what online classes are like. I didn't choose to do them ALL online, as I like the interaction in class. I am also a bit worried about how much more boring it could be online....anyway....wishing you all a safe and happy holiday!
