I passed my 10th with first class in year 1992
I was unable to pass my 12th exam and I quit studies after that due to some unavoidable reasons.
I wish to restart my education and now I checked in varous forums that it is mandatory to clear 10+2 to enrol for any graduate course.

I checked all options and decided to take up and complete 12th through NIOS-sr secondary option.
How to go about it and where to start?
I live in Bangalore and I am working and cannot quit my job due to family.
