I am studenof class 12 bihar board and i have 5 main subject and 1 additional subject and i got more marks in additional subject....can i replace my hindi with my additional subject (computer science) Because I have to be in the top 20 percentile for JoSAA counselling.

Hey,

Yes, for Bihar Board, your additional subject (Computer Science) can usually replace a lower-scoring subject like Hindi in the overall “best 5” percentage calculation if you scored higher in it.

But for JoSAA eligibility/top 20 percentile calculation, there’s one important thing:
• Physics, Chemistry, Mathematics, and one language subject are compulsory
• The 5th subject can be your additional subject like Computer Science

So Computer Science can improve your aggregate, but you still need at least one language subject (Hindi or English) to remain included in the final calculation.

If your updated best-5 percentage crosses the Bihar Board top 20 percentile cutoff, then it can help for JoSAA eligibility .
