where I can get admission in Bhubaneshwar for btech with 70 percentage
Hello Pratyush,
First of all congratulations.
Coming to your question, I am guessing you are talking about your 12th percentage, if not so then, please clarify. You have to look out for JEE rank in order to get into an engineering college. If you will get good rank then you can get admission in really good colleges in Bhubaneswar.
Hope this helps. All the very best for your future endeavours.
