What is BITSAT 2026 Iteration 4 Counselling?

BITSAT 2026 counselling is an iteration-based seat allotment process run entirely by BITS Pilani on its official portal. Unlike centralised systems such as JoSAA, students register once, submit campus-programme preferences in order of priority, and the system allots seats automatically across successive iterations. Iteration 4 is the fourth such round, offering seats that became available after students declined or forfeited allotments in Iterations 1, 2, and 3.

Students already holding a seat from an earlier iteration may receive an automatic upgrade in Iteration 4 if a higher-ranked preference opens up. Students who did not receive a seat in previous rounds are also considered for available vacancies based on their merit rank derived from BITSAT score and Class 12 PCM marks.

How to Fill Branch Preferences for BITSAT 2026

Branch preference filling is a one-time step in BITSAT 2026 counselling. Your submitted preferences determine seat allotment across all iterations including Iteration 4. If you filled preferences before the June 5 edit window closed, no further changes are possible. Students submitting preferences for the first time should follow these steps.

1. After logging in, go to the Preference Form or Choice Filling section.
2. Browse all campus-programme combinations available across Pilani, Goa, and Hyderabad campuses.
3. Rank all combinations in strict order of preference — your most desired programme goes at Position 1 and others follow in descending order of preference.
4. Add at least 15 to 20 choices to maximise your chances across all iterations, including lower-preference combinations that improve your probability of a seat in later rounds.
5. Review all entries carefully before submitting.
6. Lock and submit the preference form before the deadline. Preferences cannot be changed after the edit window (June 3 to June 5, 2026) closes.

Your merit rank is calculated using a weighted formula combining your BITSAT score and Class 12 PCM aggregate. The system automatically allots the highest-ranked available preference for which you are eligible in each iteration.
