BITSAT Choice Filling 2026, Counselling & Registration Process

BITSAT Choice Filling 2026

BITSAT 2026 is one of India's most competitive engineering entrance exams, conducted by Birla Institute of Technology and Science (BITS), Pilani. After qualifying the exam, the next critical step is the BITSAT choice filling and counselling process, where students select their preferred programmes and campuses. With the official 2026 admission schedule now released, this guide covers every key date, step, and document you need to know to navigate the BITSAT admission process 2026 with confidence.

What Is BITSAT Choice Filling 2026?

BITSAT choice filling is a central part of the BITSAT admission process. It is the step where qualified candidates log in to the official BITS Pilani admissions portal and submit their ranked list of preferred degree programmes and campuses. BITS then uses these preferences along with each candidate's BITSAT score to carry out seat allotment through a series of iterations.

Key things every applicant should know about the BITSAT choice filling process:

• Only candidates who qualify BITSAT 2026 and meet the minimum eligibility requirement of 75% aggregate marks (or equivalent board rank) in PCM in Class 12 can participate.
• Eligible candidates can choose from BE, B.Pharm, and M.Sc. (Hons.) programmes offered across the Pilani, Goa, and Hyderabad campuses.
• The preference window for 2026 opened on 29 April 2026 and closes on 1 June 2026.
• A short editing window (3 June to 5 June 2026) allows candidates to revise submitted marks and preferences. No changes are permitted after 5 June 2026 under any circumstances.
• Choices must be locked before the deadline. Preferences that are saved but not locked are not considered for allotment.

The order in which you list your preferences matters enormously. Seat allotment is done strictly on merit and preference order, so always put your most desired programme and campus first.

Important Documents Needed for BITSAT Choice Filling

Before starting the choice filling and application process, gather all required documents in advance. Missing or incorrectly uploaded documents can cause delays during verification or result in the cancellation of an allotment.

Note: Exact document formats, sizes, and any additional requirements may vary. Always verify the latest specifications on the official BITS admissions portal at admissions.bits-pilani.ac.in before uploading.

BITSAT Counselling 2026

The BITSAT counselling 2026 process is conducted entirely online through the official BITS Pilani admissions portal. BITS does not hold a physical counselling event.

Here is how the overall BITSAT counselling process works for 2026:

• Eligible candidates apply for admission by submitting their 12th marks and preferences on the admissions portal. This step combines registration and choice filling into one online form.
• After the preference window closes, a brief editing phase (3 to 5 June 2026) lets you correct any errors in marks or preferences. After 5 June, the data is locked permanently.
• BITS Pilani processes all applications and publishes the Iteration-I seat allotment result on 15 June 2026.
• Allotted candidates must pay the required fee or advance fee by 22 June 2026 to confirm their seat in Iteration-I.
• Subsequent iterations (Iteration-II, Iteration-III, and so on) are held in July and August 2026, as per official announcements, to fill vacated or unfilled seats.

• Board marks may be used as andidates must pa tiebreaker in specific situations, per BITS Pilani norms.
• After each iteration, candidates who were not allotted a preferred option or who wish to slide to a higher preference remain in the pool for the next iteration automatically.
• Candidates who accept a seat but miss the fee payment deadline will forfeit their allotment. There is no grace period.
