Hello Rajeev,,

Hope you are doing well.

You have music as your 5 the optional paper.
Your music will be counted for percentage calculation as the 5 the subject with higher marks is always counted to make a percent for admission in any colleges in India.
The best of the two is choosen and then the percentile is calculated.
Nits would too do the same.. and your 77 print would be considered.

So Stay relaxed and tension free.

Good luck.

Greetings from Careers360. Your music percentage is not considered when calculating % for 12 at NITs or IIT's admission. So, 73% will be counted in for admission. Good luck :)
