Historically, IISER Entrance Exam has maintained a consistent annual timeline, making it easier for aspirants to anticipate important milestones for the upcoming 2026 cycle. Typically, the official notification for the IISER Aptitude Test is released around February-March. The registration process usually begins in March and concludes by April. The examination itself is generally conducted in May. For instance, in 2024, the application portal opened on April 1, and the last date to apply was May 13. The IISER Aptitude Test 2024 was held on June 9, and the results were published on June 25. The counseling registration for 2024 began on June 26, with the first round of admission offers starting on July 7. Similarly, for 2025, the notification was out in February, registration started on March 5, the exam was on May 25, and results on June 24. This predictable schedule allows prospective candidates to plan their academic year effectively, dedicating specific periods for notification tracking, application submission, and intensive exam preparation. By reviewing past schedules, aspirants can set realistic preparation goals and stay ahead in their IISER Entrance Exam journey.

Among the many dates in the IISER Entrance Exam 2025 schedule, a few stand out as absolutely critical to a candidate’s success. The application submission deadline, which for 2025 was April 15, is a primary checkpoint as missing it leads to disqualification from the current admission cycle. Equally vital is the admit card download window, which opened on May 15, 2025, since the admit card is mandatory for entry into the examination hall. The IISER Aptitude Test itself, held on May 25, 2025, represents the culmination of preparation and the direct determinant of eligibility for further stages. Post-examination, the result declaration on June 24, 2025, is a significant milestone, as it confirms qualification and rank. Finally, the counselling and seat allotment dates, with the first round allotment commencing on July 21, 2025, are crucial for securing admission to the desired IISER institute. Missing any of these deadlines may result in disqualification or missed opportunities in the admission process. By staying alert to these high-impact deadlines, aspirants can avoid last-minute stress and ensure they remain on track for every stage of the IISER Entrance Exam process.

Once the IISER Entrance Exam 2025 concludes, the post-exam process begins with the release of the provisional answer key. For the 2025 cycle, the provisional answer key was displayed on May 26, 2025, shortly after the examination. Following this, candidates were provided a specific window, from May 29 to June 1, 2025, to raise any objections against the provisional answers. These objections are carefully reviewed by the examination authority. After thorough consideration of the objections, the final answer key was released on June 24, 2025. Concurrently, the IISER Aptitude Test 2025 results were also declared on June 24, 2025. For examinations conducted in multiple slots, a normalization process is often applied to ensure fairness and equity in scoring, though the IAT 2025 was held in a single shift. Successful candidates, based on their ranks, were then invited for the counseling process. The registration for counseling commenced on June 26, 2025, and the first round of seat allotment offers was announced on July 21, 2025. Subsequent rounds of counseling and seat allocation continued until August 2025, facilitating admissions into various BS and BS-MS dual degree programs. This structured post-exam process ensures transparency, fairness, and a smooth transition from test-taking to admission.
