Some people could do it but I don't think it is advisable. If you are working full time then that would mean around 9 hours most days including to getting to and from work. Then if you are going to school full time that could mean around 7 or more hours per day for classes and labs. That sort of schedule doesnt leave much room for studying and homework, laundry and other junk you gotta do, sleeping, time with partner or family, and so on.
My opinion is that you should consider doing one full time and the other part time. And remember that living is almost as much about managing money as it is the actual amount of money a person gets.
