CSAB 2026 Mathematics and Computing Vacant Seats: Real Data by NIT/IIIT/GFTI

329 Mathematics and Computing vacant seats confirmed across NITs, IIITs, and GFTIs going into CSAB 2026 Special Rounds — extracted directly from CSAB's official tentative seat vacancy document.

Mathematics and Computing Vacant Seats — The Real Numbers

CSAB publishes a "Tentative Seat Vacancy" document ahead of each Special Round, listing every institute-program-quota-category combination that has at least one unfilled seat. We filtered and aggregated every Mathematics and Computing row from the official 2026 document — summed by institute type and by institute — to give a genuine, numbers-first picture of where Mathematics and Computing seats are actually going unfilled.

The headline number is 329 vacant seats across every quota, category, and seat pool combined. GFTIs account for the largest share at 170 seats (52%), followed by IIITs at 96 (29%) and NITs at 63 (19%). GFTIs leading follows the pattern seen across most CSAB branches — their sheer breadth as a category, spanning over 30 institutes of varying reputation and demand, naturally produces a larger vacant pool, while Mathematics and Computing remains a comparatively niche, specialized program at both NITs and IIITs.

Remember: this is a tentative snapshot, exactly as CSAB itself labels it. The document explicitly notes that "candidates may also fill those choices which are not listed in this table" — meaning zero-vacancy rows aren't necessarily permanently closed, and the list updates as SR1 and SR2 progress. Use it to calibrate realistic expectations, then verify the live figure on csab.nic.in before locking your final choice list.

How to Use This Data

  • This is a tentative snapshot, not a live feed — CSAB updates the vacancy list as SR1 and SR2 progress.
  • Absence from the list doesn't mean zero vacancy — CSAB's own document says candidates may still fill choices not listed.
  • Use vacancy to calibrate expectations, not as a guaranteed cutoff predictor — always run your rank through the CSAB college predictor for a personalized estimate.
  • Cross-check the live number on csab.nic.in before finalizing your choice list — figures shift as candidates report, float, or withdraw.

CSAB 2026 Mathematics and Computing Vacant Seats – FAQs

Common questions about Mathematics and Computing vacant seat data in CSAB 2026 Special Rounds

1
How many Mathematics and Computing vacant seats are there in CSAB 2026?
The official CSAB 2026 tentative seat vacancy list shows 329 Mathematics and Computing vacant seats going into the Special Rounds. GFTIs account for the largest share at 170 seats (52%), followed by IIITs at 96 (29%) and NITs at 63 (19%). This is a tentative, point-in-time snapshot published by CSAB — the actual number shifts slightly as SR1 and SR2 progress and candidates report, float, or withdraw.
2
Which institute type has the most Mathematics and Computing vacant seats?
GFTIs lead with 170 vacant Mathematics and Computing seats — just over half of the total. This mirrors the pattern seen across most CSAB branches, where GFTIs as a group carry the largest share of vacancies simply because they include over 30 institutes of varying demand levels. IIITs (96 seats, 29%) come next, since Mathematics and Computing is a niche but present offering at several IIITs, while NITs (63 seats, 19%) offer it at comparatively fewer campuses.
3
Which institute has the most Mathematics and Computing vacant seats?
Birla Institute of Technology, Mesra, Ranchi tops the list with 52 vacant Mathematics and Computing seats, closely followed by Central University of Jammu (48) and IIIT Bhagalpur (42). BIT Deoghar Off-Campus (29), IIIT Vadodara (28), and IIIT Raichur (26) round out the top six. Four of the top six are GFTIs or newer IIITs, reflecting that Mathematics and Computing as a specialized branch draws less uniform demand than core CSE or ECE programs.
4
Is Mathematics and Computing easier to get through CSAB Special Rounds?
A vacant pool of 329 seats — smaller than CSE's 3,189 or even IT's 328 — reflects Mathematics and Computing's status as a niche, specialized branch offered at fewer institutes overall. Lower absolute vacancy doesn't automatically mean easier admission though; it depends heavily on which specific institute and category you're targeting. Use this data to calibrate realistic expectations, not as a direct cutoff predictor.
5
Is this Mathematics and Computing vacant seats data official and current?
Yes — this page is built directly from CSAB's own official "Tentative Seat Vacancy for CSAB Special Rounds 2026" document, filtered specifically to Mathematics and Computing program rows. CSAB explicitly states vacant seats listed are tentative and candidates may also fill choices not listed in that table. Because CSAB updates this list as the Special Rounds progress (SR1 vs SR2 vacancy differs), always cross-check the live figure on csab.nic.in before finalizing your choice list.
6
Why do GFTIs dominate Mathematics and Computing vacancies over NITs?
GFTIs contribute 170 of the 329 total Mathematics and Computing vacant seats (52%) versus just 63 at NITs (19%) mainly because relatively few NITs offer Mathematics and Computing as a distinct branch — it's typically a smaller, specialized program compared to core branches like CSE or Mechanical. GFTIs, being a much larger and more varied group of over 30 institutes, collectively offer more Mathematics and Computing seats in total, and several of those institutes see comparatively lower applicant demand, driving up their vacancy share.
