Hey!
I dont understand your question. i dont think you asked what you wanted.
when you have already passed class 12 from UP board, why do you have to appear again as a private candidate from CBSE?
either you must have studied in CBSE or In UP Board.
to be honest, you can do that, but why? mark is mark. the board from you are doesnt matter in college.
i hope it helps you
