dolphingirl, have you been doing school & work and now you're just upping your credit hours? or are you just starting with either school or the job?

I did both school & work for several years, I have to admit I had my ups and downs. If you're just starting school, I would take it slow and do one less class than you are planning, especially if you are already worried about it. 18 credits is a lot!

Also try to make sure you have a balanced course load, with some classes that are easy for you or more interesting. I also like to schedule myself an hour or two break in between classes for study time. This will force me to hit the library and get some work done, whereas if I wait till after work/class I will find any excuse not to study.

Good luck!
