Why Round 4 Matters in the IISER Counselling 2025 Journey

Round 4 of IISER admissions carries particular weight for students who narrowly missed their preferred choices in earlier rounds. According to officials, this round is expected to clarify the availability of highly competitive BS-MS and BTech seats, as withdrawals from earlier rounds are processed.

The counselling process itself is built upon the IISER Aptitude Test (IAT) ranks, and the decision to shift the allotment date was accompanied by a revised schedule for acceptance and admissions. Candidates now have from August 18 to August 21 to confirm their seats, pay the required fee, and prepare for document verification.

In a statement shared by an IISER admissions committee member, “The rescheduling of the allotment is a technical necessity. We assure students that no disadvantage will arise from the two-day shift. The counselling system remains transparent and all seat offers will be honored as per the revised timeline.”

Key Details of the Rescheduled Seat Allotment

• New Date for Round 4 Seat Allotment: August 18, 2025
• Seat Acceptance Window: August 18–21, 2025
• Acceptance Fee: ₹35,000 for general category; ₹17,500 for SC/ST candidates
• Total Seats Across IISER Campuses: 2,363 (BS-MS, BTech, and BS Economics combined)
• Final Rounds: Two additional rounds (Round 5 and potential Spot Round) expected after Round 4

This decision was uploaded on the IISER admissions portal, ensuring that students had updated instructions on how to proceed with their applications.

Financial Aspects: Seat Acceptance Fees Explained

One of the crucial elements of this update relates to the IISER 2025 seat acceptance fee ₹35,000 vs ₹17,500 SC/ST. This non-refundable fee ensures that a student secures their allotted seat.

For General, EWS, and OBC-NCL categories, the amount remains ₹35,000. However, in an attempt to ensure inclusivity, IISERs have set a reduced fee of ₹17,500 for SC and ST candidates.

Financial aid policies also vary by campus, with many IISERs offering tuition fee waivers or scholarships post-admission. Prospective students are encouraged to check campus-specific fee structures and financial support options.

Seat Availability: Breaking Down the Numbers

The IISER admission process began with 2,363 seats spread across the seven institutes:

• IISER Pune – BS-MS, BTech, and Economics streams
• IISER Bhopal – BTech in Engineering Sciences alongside BS-MS
• IISER Kolkata – Core focus on BS-MS and interdisciplinary courses
• IISER Mohali, Berhampur, Tirupati, and Thiruvananthapuram – BS-MS and research-driven streams

The IISER IAT counselling four rounds seats 2363 across campuses have now narrowed down considerably. By Round 3, many of the top seats in popular streams like Physical Sciences, Engineering Sciences, and Computer Science were already filled. Round 4 thus provides a second chance for students ranked slightly lower to secure a seat.

Revised Admission Schedule: August 18 to 21

Candidates must complete formalities between August 18 and 21 to confirm their admissions. This window, officially referred to as the “seat acceptance phase,” allows students to pay fees, upload documents, and download admission letters.

The IISER 2025 admissions schedule Aug 18 to 21 and process includes:

1. Logging into the IISER counselling portal.
2. Reviewing the seat allotment result for Round 4.
3. Paying the seat acceptance fee within the specified deadline.
4. Uploading required academic and category certificates.
5. Downloading the provisional admission offer letter.

Failure to complete these steps by the deadline will automatically lead to seat cancellation, with the opportunity passed to the next eligible candidate.

Student Perspectives on the Postponement

Students expressed mixed emotions on social media and education forums. For some, the delay meant additional anxiety in an already stressful admissions season. For others, the two-day extension offered extra time to prepare necessary documents and confirm financing arrangements.

Ritika Sharma, an IISER Bhopal aspirant from Delhi, shared on a student forum, “The wait has been tough, but I am glad the portal issues are being fixed before Round 4. At least we now have a clear date.”

Expert Insight: Impact on Closing Ranks

Education analysts point out that the IISER Round 4 seat allotment postponed to August 18 2025 could impact closing ranks. Historically, Round 4 is where cut-offs dip slightly, giving borderline candidates a chance to secure seats in reputable programmes.

Dr. Ajay Mehta, an academic counsellor and researcher in higher education policies, explained, “The final two rounds are crucial for aspirants with mid-level ranks. With 2,363 total seats, Round 4 could bring closing ranks down by 5–10% across some streams.”
