Hello Aspirant,

See your overall percentile of JEE-Main cannot be calculated from the separate percentiles of the three subjects. Let me explain you, why. See percentile is simply the percentage of students scoring equal to or less than the score that you have scored in JEE-Main and this criteria is implied for each of the three subjects as well as for overall percentile. So as you have scored 95 percentile in Mathematics and Chemistry, which means that 92% students have scored either less than or equal to you in Mathematics and Chemistry part of JEE-Main 2021. From the data given by you it is not there that how much marks in total you got and your overall percentile and rank will only be decided on the basis of what marks have you achieved as per the answer key of JEE-Main 2021.

However you can check out marks Vs CRL ranks Vs Percentile from the link given below :-

Or

You can also use JEE-Main Rank Predictor to predict your rank :-

You can check out the link given below to check whether based on your overall percentile and rank you will get any NIT with CSE branch or not :-

Also I am mentioning down the expected cut-offs for this year to give you an idea whether you will qualify for JEE-Advance or not :-

• Common Rank List (CRL) - 90- 95 Percentile
• GEN-EWS - 70- 75 Percentile
• Other Backward Classes (OBC-NCL) - 70- 75 Percentile
• Scheduled Caste (SC) - 50- 55 Percentile
• Scheduled Tribe (ST) - 40- 45 Percentile
• PwD - 1-2 Percentile

So if you belongs to general category then you should have at least 90+ percentile in JEE-Main in order to get qualified for JEE-Advance.

Note that in above table it is not the actual cut-off for JEE-Main 2021 but expected on the basis of previous year's analysis. You can check out previous year's cut-off trends from the link given below :-

I hope this information helps you.

Good Luck!!
