A degree program in India is generally a three-year one. Two-year programs are offered only as a diploma or a certificate course. A two-year degree program would depend on your earlier academic record, that is, if you have any college credits from before you dropped out of college. It also depends on the norms of UGC and the university with which the college is affiliated. These norms will need to be adhered to for pursuing a shorter-duration degree program, including what is known as an accelerated degree program. Note also that some employers do insist on a three-year degree program being successfully completed after Class 12, and not a two-year one. I have seen recruitment advertisements making this an essential criterion.
You do have the option of pursuing an online course that could get you a degree within two years, but this has a major drawback. You will find it difficult to get a job as most employers, including educational institutions, may not accept any degree obtained through online mode.
I would advise you to complete your college education properly through a valid three-year program if it is a Degree that you are seeking. Diplomas, of course, are acceptable, too, by some employers, but not by all.
It is suggested that you share more information, namely, up to which Class you studied (have you completed Class 12?), the stream in which you studied (Arts/Science/Commerce), and which field you are interested in completing your college studies. Perhaps you can pursue a 3-year vocational degree program also. Then, once you give the details, accordingly, further guidance can be given. Specific colleges/universities can also be suggested if you let us know in which city/State you are based.
Do not give up on trying to complete your education. Stick to your goal.
