Delhi University admits its undergraduate students through the Common Seat Allocation System (CSAS), which works in phases. Understanding these phases — especially the preference-filling step — helps you avoid mistakes that can cost you a seat. Here is how the process works and how to approach each part.
The phases of CSAS, explained
- Phase 1 — Registration: you register on the CSAS portal and fill in your details and academic information.
- Phase 2 — Preference filling: after CUET results, you select and order your preferred combinations of programme and college.
- Phase 3 — Seat allocation and admission: DU allots seats based on your CUET score, your preferences and availability, and you accept and complete admission.
Why preference filling is the crucial step
In the preference phase, you choose combinations of course and college and rank them in order. DU allots you the highest available combination on your list, so the order matters enormously. A great CUET score can still lead to a disappointing seat if your preferences are ordered carelessly.
How to fill preferences well
- Add every programme-and-college combination you would genuinely accept.
- Order them in your true preference — most-wanted at the very top.
- Do not leave out combinations just because you think you might not get them.
- Review carefully and submit before the deadline, then save the confirmation.
After allocation
When a seat is allotted, you accept it within the given window and complete the admission steps, including any fee payment, on the official portal. In later rounds you may get an upgrade based on your higher preferences, so read the rules for accepting and upgrading carefully.
Frequently asked questions
Does a high CUET score guarantee my preferred college?
Not on its own — allocation also depends on how you order your preferences and on seat availability. Ordering your genuine favourites at the top is essential to getting the best possible seat.
Where do I complete DU UG admission?
Only on the official DU CSAS portal. Register, fill preferences, and pay any fees there, and be cautious of any unofficial site or agent.
