Hey,

For admissions in undergraduate courses the eligibility criteria specifies that the candidate should have passed the 12th or qualifying examination in the same year or a year before taking the exam. Thus, for admissions in undergraduate courses you can apply for only 2 times.

I hope this helps.

All the best!

Hey!

There is nothing such mentioned on the official site of IISc. You can apply after your first attempt of jee or 3rd attempt of jee, it doesn't make difference. You just have to be eligible for the admission criteria of IISc for the required course. For more information you can visit the official website of iisc.

Thank you.
