Dear Student,
Glad to inform you that you can definitely continue your studies part time or even from home through various distance learning programs offered by various universities at national and international level. The most popular and old of them is IGNOU. Many universities specially government universities have only 3-4 hours classes for it's Full time courses even, so you shall go for it if you can manage. I suggest you to look after any government college in your city only as private colleges have a bit hectic schedules or else go for Distance learning program from a good university.
Hope this might help you.
