Hi Sourav,
Which stream are your from?

It's up to you, what your area of interest is and your aim, in which field you want to take your career, etc.
You have number of options to choose:
If you got good percentage, somewhere more than 85% then my suggestion is you should go for regular college in DU and after that MBA through CAT/XAT.
Or
You can go for professional courses such as CA/CS/ICWA along with graduation from correspondence.

Hi Priyanka,
If you are keen to complete your HSC you may enroll in an open schooling such as NIOS and pursue the same. You can also check out diploma or vocational programs to develop your skills set.

Hi Hamza, please clarify your stream, whether you are from Arts, Science or Commerce so that I can suggest you better. Also, specify your interest and career orientation when you say career prospects.
