CSAB 2026 Choice Filling Tips – Strategy for Special Round (Concluded)

CSAB 2026 Special Rounds (SR1 and SR2) operated on the leftover vacant seats after JoSAA 2026 concluded on July 16. The choice filling process was similar to JoSAA but with fewer candidates competing, which meant relaxed closing ranks. Here is the strategy guide that applied — useful as a reference for how the round played out and for future CSAB cycles.

Step 1 – Know the Available Seats

Before filling choices, candidates checked the CSAB 2026 seat matrix released on csab.nic.in. The matrix showed exactly how many seats were vacant in each institute, branch, and category. The advice was to focus only on seats available in your category — not waste choices on zero-vacancy combinations.

Step 2 – Use Previous Year CSAB Cutoffs as Benchmarks

Step 3 – Build Your Choice List (Order Matters)

• Top of list: Dream college+branch combination (even if slightly reach).
• Middle of list: Realistic colleges where rank comfortably fell within CSAB cutoff.
• Bottom of list: Safe fallback options — colleges where the rank was well within cutoff.
• Always include: Home-state quota (HS) options if applicable — home state quotas typically had significantly lower cutoffs.

Common Mistakes That Cost Candidates

• Not filling enough choices — the benchmark was at least 50 unique combinations.
• Filling the same college multiple times with different branches without strategising branch priority.
• Ignoring home-state quota options — HS quota could drop cutoffs by 2,000–5,000 ranks.
• Assuming CSAB cutoffs were the same as JoSAA — they were typically more relaxed.
• Missing the lock-choices deadline — unsubmitted choices were treated as not participated.
