For the aforementioned reasons, don't go to school if you have to quit your job. There are plenty of training courses you can take, especially in computers, that do not require full-time attendance. These may include evening & weekend courses, or distance-education courses. There are lots of options if that is your interest, and you shouldn't have to quit your job.

My problem is *engineering* which requires full-time attendance. Ludicrous. I strongly believe that full-time attendance is not necessary. Hands-on type (laboratory) assignments could be done in a few weekends on campus, all other work can be done at home with pre-prepared course material. Engineering is the last hold-out of antiquated and elitist education systems, there really isn't anything special about it. But that probably doesn't affect you. Sorry if I seem so serious tonight, I am just in a serious mood.
