CSAB Round 1 Seat Allotment Predictor 2026

Predict your CSAB Special Round 1 (SR1) allotment based on JEE Main rank and category. SR1 reporting ran August 6–11, 2026, and SR2 result was declared August 12, 2026.

Understanding CSAB Round 1 Allotment

CSAB 2026 conducted 2 main special rounds after JoSAA concluded its 5 rounds in July 2026. Special Round 1 (SR1) reporting ran August 6–11, 2026, and SR2 result was declared August 12, 2026. SR1 was the first opportunity to receive a seat allotment through CSAB, based on your choice list and available seats.

The SR1 prediction uses CSAB 2025 Round 1 closing ranks as the primary benchmark. Since CSAB SR2 sometimes has slightly different cutoffs (some candidates withdraw after SR1, freeing seats), SR1 predictions give you the best indication of your immediate options.

After receiving your SR1 allotment:

  • Accept and participate in SR2: Pay the seat acceptance fee; you can still upgrade in SR2.
  • Accept and withdraw from SR2: Satisfied with SR1 allotment — keep the seat.
  • Do not accept: You lose eligibility for CSAB SR2 and forfeit your chance entirely.

Never skip acceptance — always pay the fee by the deadline, even if planning for SR2.

Frequently Asked Questions – CSAB Round 1 Predictor 2026

Common questions about CSAB Round 1 seat allotment

1
When was CSAB Round 1 seat allotment in 2026?
CSAB Special Round 1 (SR1) reporting ran August 6–11, 2026, after JoSAA Round 5 concluded on July 16, 2026. CSAB registration and vacancy display opened July 28, 2026, with choice locking closing August 5, 2026. SR1 is now complete; the SR2 result was declared August 12, 2026. Always verify exact status at csab.nic.in.
2
How is CSAB Round 1 allotment different from Round 2?
CSAB Round 1 is the initial allotment based on registered candidates' choice lists and available seats. After Round 1, candidates can accept their allotment and participate in Round 2 (for a potentially better seat) or withdraw. Round 2 uses the same registered choice list but with updated seat availability — seats vacated by candidates who withdrew or did not accept in Round 1 also become available.
3
Should I accept my Round 1 CSAB allotment if I am not happy with it?
Yes, if you want to remain eligible for Round 2. In CSAB, if you receive an allotment in Round 1 but do not accept it, you forfeit your right to participate in CSAB Round 2. Always accept the Round 1 seat (by paying seat acceptance fee) even if you are hoping for something better in Round 2. Your Round 1 seat serves as a safety net.
4
Can CSAB Round 1 cutoffs be higher than JoSAA Round 5 cutoffs?
Generally no — CSAB cutoffs are typically higher numerically (weaker ranks) than JoSAA Round 5 because CSAB handles leftover seats. However, in rare cases for specific institutes, CSAB Round 1 may see more competition if many JoSAA dropouts register for CSAB simultaneously. This can occasionally push CSAB Round 1 cutoffs slightly tighter than expected.
5
What documents do I need for CSAB Round 1 acceptance?
For CSAB Round 1 acceptance: JEE Main 2026 rank card, Class 10 certificate (DOB proof), Class 12 mark sheet, category certificate (SC/ST/OBC-NCL/EWS if applicable), recent passport-size photograph, and proof of seat acceptance fee payment. Documents are verified online; physical reporting may come later depending on CSAB 2026 guidelines.
