I can’t give a single exact “cutoff for OC in top 110 colleges” because JEE Advanced cutoffs vary by IIT, branch, round, and whether you mean qualifying cutoff or admission cutoff. For a practical estimate, OC candidates usually need a much stronger rank than just clearing the qualifying mark, and the top branches in the top IITs close at very low AIRs, while lower-demand branches can go much farther.

What this usually means

  • Qualifying cutoff : the minimum marks/rank needed to be considered eligible for IIT admission.
  • Admission cutoff : the closing rank for a particular IIT and branch during JoSAA counselling, which is the number most students actually care about.

Practical OC estimate

  • For top IITs and top branches like CSE, the closing ranks are extremely competitive.
  • For the broader set of roughly top 110 IIT/branch combinations , the cutoff can range widely depending on seat count, category, and round.
  • A safer way to think about it is: OC needs a rank well inside the IIT-eligible zone, not just the qualifying cutoff.

Best way to read the cutoff

  • If you want IIT admission chances , check branch-wise closing ranks from JoSAA, not only the qualifying cutoff.
  • If you want eligibility , check the category-wise expected cutoff for OC/General.

Important note

Because your wording mixes “cutoff” and “top 110 colleges,” the answer depends on whether you mean 110 colleges overall or top 110 IIT branches. The first is not a standard JEE Advanced metric, while the second is usually handled through opening/closing ranks in JoSAA data.

Quick answer: for OC, clearing JEE Advanced is not enough for the best IIT seats; you usually need a significantly better rank, and the exact cutoff depends on branch and counselling round. You can ask for a **branch-wise OC cutoff list for top IITs** or a **rank estimate from your marks**.
