Dear Prakash, if you have had 90% results in 10+1, you cant even have a faint doubt of imagination of your 10+2 results. And to appear for any entrance examination, you necessarily neednt need the qualifying exam results. You should have passed/completed the highest qualification and have the certificates during the time of counselling and admission. Please attend the entrance examination and by the time the results of the entrance exam are released you will also have your 10+2 results handy. But dont miss the entrance examination.
