What is a Good Attempt in IISER 2026?

After taking the IISER Aptitude Test (IAT) 2026, many students are anxious about whether they will qualify for the examination and secure admission to prestigious research institutes such as IISERs, IISc, IITs, and other IAT 2026 participating institutes.

The IISER 2026 result is expected to be released approximately one month after the examination. However, the admission authorities do not release any official IAT 2026 cut-off marks immediately after the result declaration. Candidates can only determine their admission status after the counselling and seat allotment process is completed. This often results in a long waiting period for aspirants.

To help candidates assess their performance and estimate their chances of admission, we have analyzed previous years' exam trends, cut-offs, and admission data. Based on this analysis, here are the details of a good score in IAT 2026 and the expected admission chances across various institutes.
