First of all, I congratulate you on your decision that you are interested to start your education afresh even though a long gap has occurred in between. However, it is an encouraging step to think seriously in this line.
There are a lot of universities offering you the distance education course in the direction you want to move such as Humanities, Science and commerce as for example. To name a few of such universities are IGNOU, Karnataka Open University, Manipal Distance Education, Utkal University Distance etc. Of all I think, IGNOU would be a better choice since you need move elsewhere for the course- materials to be taken up by you at the different stages of your continuation of course.
The subject - materials provided by them are of immense value since this would provide you clarity of subjects of the different subjects included in your course. The other interesting feature with your continuation with this open university is that you will be backed up with the doubt removal classes of one month which will follow before the end of the course for all the courses undertaken by you be it intermediate or graduation.
You need to devote your time for at least five years for completing your graduation course right from now but with their guidance, you will have your degree in a stress - free environment.
