On Question asked by student community
Hello,
Yes, you can be eligible , but it depends on how you passed Mathematics.
JEE Main
You are eligible if:
You passed Class 12 with Physics and Mathematics.
Mathematics was passed as a full subject from NIOS.
NIOS is a recognized board.
Having two marksheets is allowed.
You are not eligible if:
Mathematics was taken only as an improvement or additional without passing it as a full subject.
MHT-CET
You are eligible if:
You passed Class 12 with Physics and Mathematics.
Mathematics from NIOS is shown as a passed subject.
NIOS is recognized for Maharashtra admissions.
Mathematics was passed before the admission year.
You are not eligible if:
Mathematics is not shown as a passed subject.
Important
Mathematics must be a separate and passed subject.
Keep both marksheets during counselling.
Always check the current year information brochure before applying.
Hope it helps !
The marks needed for a 99+ percentile in the JEE Main January attempt depend on the difficulty of the paper and the total number of candidates. Generally, you need roughly *180–200* marks out of 300 to hit the 99+ percentile. The exact cutoff varies each session, so checking the official NTA percentile score calculator or previous year cutoffs gives a more precise idea.
Hello aspirant
JEE Main accepts NIOS, so you can appear if you meet the basic eligibility.
BITS does not accept marks from two different boards, so this option won’t work for BITS.
VIT and SRM generally accept NIOS, but having two separate mark sheets can be an issue. You should check their official eligibility rules before applying.
Thankyou I hope this help
