Can a student apply for CBSE 12th improvement exam for 2017 and in the meantime take admission in a b.sc or b.tech course as well?
Yes, you can apply but make sure that before the counselling for B.tech or the admission for B.Sc in any of the college you should have your improvement result with you.
Good Luck!
but it very tuff to handle both college and school syllabus!
