I dropped out of college a decade ago. How do I finish my graduation now? [Pune, India]
If you're looking for a full fledged CS engineering degree then https://www.ieindia.org/webui/IEI-Academics.aspx#academic-programme. There seems to be some court case going on. Follow this link: https://www.facebook.com/euringbishnujee.singh/ . It's still recognised though.

Any other 3 year degree you can easily do from your local university or IGNOU.

DEB site: https://www.ugc.ac.in/deb/notices.html

The distance education bureau, DEB functions under the UGC. So trust no one else but them. They have a couple of PDFs with recognised universities. Not all universities can give distance certificate. 

IGNOU: http://www.ignou.ac.in/ I've enrolled here recently.

Physically visit and interact with the staff before enrolling. 

These courses will have very few classes and they're mostly on weekends. Very doable. 

All the best.
