IAT pattern, syllabus shape and marking scheme

• Mode: Computer‑based test (CBT) .
• Total questions: 60 MCQs.

• Duration: 180 minutes (3 hours).
• Marks: +4 for correct answer, −1 for incorrect answer, 0 for unanswered.

Rank is based on total marks out of 240. Because questions are balanced across four subjects, a consistent score across sections helps. The negative marking makes selective answering safer than blind guessing.

Who is eligible — minimum marks and basic criteria

• Minimum Class XII marks: 60% for GEN/EWS/OBC‑NCL ; 55% for SC/ST/PwD .

Cutoffs and seat matrix — what last year’s ranks tell you

IISER Pune’s cutoffs (highest category ranks from recent rounds) give you a practical target for IAT ranks:

These ranks are the highest (i.e., last) ranks that got Pune in a recent round. Your aim should be well above these cutoffs to improve admission chances across rounds.

Seat distribution across IISERs (BS‑MS) — quick view:

Note: IAT 2025 had large participation — ~82,000 registered and ~78,000 appeared for an overall IAT seat pool (across channels/programmes) of 2,363 . High competition means rank targets must be realistic and backed by steady preparation.

Fees you should budget for (first semester figures)

These are the semester and one‑time charges published for the BS‑MS programme intake. Plan for refundable caution deposit and the medical insurance premium as immediate payments during admission.

How to approach IAT preparation (strategy you can use)

1. Understand the test structure. IAT gives equal weight to Biology, Chemistry, Mathematics and Physics (15 questions each). Balance your prep time across weak and strong subjects.

2. Time management in the exam. You have 180 minutes for 60 questions. Aim for steady pacing: roughly 3 minutes per question as a baseline, but adapt — easier questions take less time.

3. Negative marking matters. With −1 for incorrect answers, avoid random guessing. Use a calculated approach: attempt only when your elimination gives you acceptable odds.

4. Mock tests and sectional practice. Regular full‑length mocks train stamina. Sectional tests identify weak topics and speed issues.

5. Keep revision focused. For three months of prep, rotate subjects weekly with daily problem practice and regular mock tests in the last month.

6. Exam day routine. Rest well the day before, reach the centre early, and follow instructions on the hall ticket. Use the last hour before the test for light revision and calming your mind.

These are practical steps based on IAT’s pattern and marking scheme.

Campus life, hostels and student experience (what fees tell you)

IISER Pune charges hostel fees and has a one‑time hostel admission fee — this confirms on‑campus accommodation is available for UG students. The semester fee structure with facilities and examination charges reflects a residential campus with academic support services.

Beyond fees and numbers, IISER Pune’s larger share of students from outside the state (about 74.9% ) means you’ll meet peers from across India — useful for building an academic network early.
