I am passing 12th board 2023 but my overall marks 53% and I am going to give improvement biology from nios is this valid for neet or iiser like competitive exams??

Here are the key points regarding your query about appearing for NEET or IISER exams after passing 12th board in 2023 with 53% overall marks and appearing for biology improvement through NIOS:

1. NEET Eligibility:

- For NEET (National Eligibility cum Entrance Test), the minimum eligibility criteria is 50% marks in Physics, Chemistry, and Biology/Biotechnology subjects in the 12th board exam.

- Since your overall 12th board marks are 53%, you would be eligible to appear for NEET, provided you score at least 50% in the individual subjects of Physics, Chemistry, and Biology.

- Appearing for biology improvement through NIOS should not affect your NEET eligibility, as long as you meet the 50% criteria in the individual subjects.

2. IISER Eligibility:

- For admission to the Indian Institutes of Science Education and Research (IISERs), the eligibility criteria includes scoring a minimum of 60% marks in the 12th board exam (55% for SC/ST/PwD categories).

- With your overall 12th board marks being 53%, you would not meet the general category eligibility criteria for IISER.

- However, if you are able to improve your overall 12th board marks to 60% or above (55% for SC/ST/PwD) through the biology improvement exam, then you would become eligible to appear for the IISER Aptitude Test (IAT) 2024.

- For NEET, your 53% overall 12th board marks along with the 50% individual subject criteria should make you eligible, provided you clear the biology improvement exam.

- For IISER, your current 53% overall 12th board marks do not meet the 60% (55% for SC/ST/PwD) eligibility criteria. You would need to improve your overall marks to 60% or above to be eligible for the IISER Aptitude Test 2024.

I hope this helps provide clarity on your eligibility for NEET and IISER exams. Let me know if you have any other questions.
