Do l have to attempt biology in IISER's aptitude test? I am studying class 12th science (PCM).

Yes, while filling out the IISER Decision Making Form, it is absolutely necessary to pay the Seat Acceptance Fee (SAF). This fee is a crucial part of confirming your intent to accept the allotted seat, whether you choose the “Freeze” or “Float” option. Without paying the SAF, your seat will not be reserved, and you will be considered to have forfeited your claim to that allotment.

Moreover, non-payment of the SAF will automatically remove you from the ongoing counselling process, including eligibility for seat upgrades in future rounds. The SAF amount is later adjusted against your first semester tuition fees, so it is not an additional cost but rather an advance part-payment toward your academic expenses. Therefore, timely payment of the SAF, along with the submission of the decision form, is mandatory for securing admission or staying in the admission pool.

After you fill out the IISER Decision Making Form, the next steps depend on the option you selected—Freeze or Float:
1. If you selected Freeze:
a. Admission Confirmation
b. Your seat is considered final.
c. You will not be considered for further rounds.
2. Document Verification
a. You must upload scanned copies of the required documents via the portal.
b. Some IISERs may also ask for physical verification at the time of reporting.
c. Fee Payment
d. Pay the admission/semester fees within the given deadline to confirm your seat.
3. Reporting Instructions
a. Await an official email or update from your allotted IISER with reporting date, orientation schedule, and other onboarding details.
4. If you selected Float:
a. Seat is Temporarily Accepted
b. You retain your current seat but remain eligible for a higher-preference seat in the next counselling round.
c. Wait for the Next Allotment Round
d. If a better preference becomes available, your seat may be upgraded automatically.
