I got 89% in +2 hpboard so could I take a admission in this college.
Hey!
Your question seem incomplete. You have not specified any particular college in your question.
Anyways, your 10+2 percentage in Himachal Pradesh Board is pretty good. If you want to take admission in some university in Himachal, then you can easily get selected there.
You should browse past year cut-offs in order to get a clear idea about your chances.
Hope it helps!
