How do I fill my IAT 2026 registration form since I am a repeater and I gave my 12th boards in 2024 from PCB stream but I would be given seperate isolated maths boards exam in 2026. So, how do i fill the registration from cause i won't be getting 2026 marksheet during from registration and i gave IAT last year in 2025 as well. And would i be eligible for IISc?

Ans: Hi
Yes, you are eligible.
For IAT 2026, candidates can apply if they: Passed Class 12 in 2024 or 2025, or Are appearing in 2026.
Year of passing Class XII:
Select 2024

Qualifying exam marks:
Enter the marks from your 2024 PCB marksheet

Mathematics status:
You can mention Mathematics not studied in original Class XII if the form asks subject-wise marks.
About the 2026 isolated Maths exam: It is not required during registration.
If you later receive the marksheet, you can upload it during document verification or counselling.
Even if a candidate’s result is pending, they are allowed to apply and submit documents later.

For the BSc (Research) program at the Indian Institute of Science, the eligibility requires:
Class 12 with Physics, Chemistry, and Mathematics as main subjects.
Therefore: If you only have PCB (no maths in 12th)
You cannot get IISc admission through IAT.
