Yes you can. If there is a will, there is the opportunity. Check with a counselor at your local community college or university.
Some public and/or private universities offer evenings and weekend classes ...for those folks like you and me who have to work during the day...and want to get a degree You can also re-arrange you schedule at work ...to start early and leave early. Inquire about long distance learnig. But be careful ...make sure that the school you choose is an "accredited" college or university. Otherwise you will be wasting your time and money (student's fees etc.).
Good Luck. You can do it (work and study) ...it takes a lot of determination and discipline, don't take too many classes at a time at first, and test the waters. Also remember that some classes might be easier than others that requires a lot of research and writing reports ...if you do the undergraduate first maybe you can take more classes ...not all classes are in the evenings all the times (quarters or semesters)...so you really have to stay on top of things. It might not take you 3 years, but time goes fast ...and when you least think of it, you will be graduating with your Bachelor's Degree ...and going for your Master's. No matter how old you are ...go for it. If you have the will ...You are not competing with no anyone.
Some semesters/quarters you might take more classes if they are easier, and less classes if they are harder and require more work.
I did it while working for the worst boss from Hell ...I suffered a lot but that made me push harder and I am glad I did it. Now I work for a boss from Heavens (Knock on wood and pray to God that it stays that way) I am looking forward to retirement. I never cease to continue my education. I take continuing classes all the time.
