If you have qualified GATE CS, the next big step in your journey is participating in the Common Offer Acceptance Portal (COAP). This platform is crucial for securing admission into prestigious IITs for M.Tech programs or accepting job offers from Public Sector Undertakings (PSUs).
In this detailed COAP 2026 registration guide, we will explain everything in simple English—from eligibility to step-by-step registration, important rules, mistakes to avoid, and expert tips.
This guide is specially useful for students preparing with Gate At Zeal Indore and all GATE CS aspirants who want clarity on what to do after results.
What is COAP?
COAP (Common Offer Acceptance Portal) is a centralized platform created by the IITs.
It is used to:
- Accept/reject M.Tech admission offers from IITs
- Accept/reject PSU job offers (like IOCL, BHEL, etc.)
Important:
COAP does NOT handle applications.
You must apply separately to IITs and PSUs.
COAP is only for:
✔ Viewing offers
✔ Deciding (Accept/Reject/Hold)
