DU CSAS 2026 Choice Filling: How to Rank Colleges and Courses

DU CSAS 2026 choice filling is set to open in the first week of July 2026 — ranking your college and program choices from most ambitious to safest, and locking them before the deadline, gives you the best chance of securing the seat you actually want.

Delhi University’s Common Seat Allocation System (CSAS) 2026 lets you fill unlimited college and program combinations in a single portal. The system allots you the highest-ranked choice for which your CUET UG aggregate score meets the closing score. Choice order matters as much as the score itself. A student who ranks the right college first at the top of their list will beat a student with a higher score who placed the same college second.

• DU CSAS 2026 Phase 1 registration opened on June 27, 2026; choice filling (Phase 2) is expected to open in the first week of July 2026.
• There is no upper limit on the number of choices you can fill — always fill more, not fewer.
• Rank choices strictly in order of genuine preference, from most desired to least desired, not by what you think you will get.
• Locking your choices is mandatory — if you only save and do not lock, your preferences are not considered for seat allotment.
• Use 2025 DU CSAS Round 1 closing scores as your primary benchmark and compare your CUET UG aggregate score before ranking each choice.

What is DU CSAS 2026 Choice Filling?

Choice filling is Phase 2 of the DU CSAS 2026 process, where you build a ranked list of college and program combinations you want to study in. The CSAS system compares your CUET UG aggregate score against the closing scores of your listed choices in the order you ranked them and allots you the first match it finds.

Each choice is one unique college-program pair. Miranda House plus B.A. (Hons) Political Science is one choice. Lady Shri Ram College plus B.A. (Hons) Political Science is a completely separate choice. You can add as many such pairs as you like, in any order, during the Phase 2 window. The order you set is the order the system uses to find your best available allotment.

Step-by-Step Strategy for DU CSAS 2026 Choice Filling

Follow these seven steps to build a choice list that maximises your chances across every round of DU CSAS 2026 seat allotment.

1. Know your CUET UG 2026 subject-wise scores — check your NTA scores for every subject you appeared in. DU CSAS computes a combined aggregate score per program using the required CUET UG subjects, so you need the individual subject scores to estimate your eligibility for each choice.
2. Map programs to their required CUET subjects — each DU program specifies which CUET UG subjects it considers. A choice filled for a program you did not appear in the correct CUET subjects for is automatically invalid regardless of score.
3. Pull up the 2025 DU CSAS closing score data — use the official previous year CSAS data for the specific college and program you are considering, not generic rank lists or percentage-based cutoffs.
4. Divide your choices into three tiers — ambitious (closing score up to 20 points above your aggregate), realistic (within 15 points either way) and safe (20 or more points below your aggregate).
5. Place ambitious choices first in your ranked list — there is zero downside to ranking a dream college at the top. If your score does not meet its closing score the system simply moves to the next choice. Your lower-ranked options are never hurt by a higher ambitious choice.
6. Add every college-program pair you would genuinely join — do not skip a choice because it seems unlikely this year. More choices means more protection across rounds if highly competitive options are out of reach.
7. Save regularly and lock before the deadline — unsaved data is lost if your session times out. Only a locked list is submitted for allotment. Complete and lock your choices at least two days before the Phase 2 window closes to avoid technical issues.

How to Rank Colleges and Courses: Key Factors

Score gap is the starting point but the following factors should shape the exact order of your choices in DU CSAS 2026.

Previous Year DU CSAS Closing Scores (2025 Reference)

The table below shows Round 1 General category closing scores for select college-program combinations from DU CSAS 2025. These are CUET UG NTA aggregate scores (sum across required CUET UG subjects for the program) from 2025 and are shared as a planning benchmark only — 2026 closing scores will vary based on CUET UG 2026 difficulty and the total number of applicants.

For the complete college and program-wise closing score list across all rounds and categories, check the official DU admissions portal after each round’s results are published.

Common Mistakes to Avoid During DU CSAS 2026 Choice Filling

• Ranking choices only around your score — always place ambitious choices above your expected range at the top of your list. The system skips them automatically if you fall short and they do not block or hurt any lower-ranked choices.
• Not verifying CUET subject eligibility — each DU program has a specified CUET UG subject combination requirement. A choice filled without the matching subjects is invalid regardless of how high your score is.
• Saving but not locking — the most common and costly error. The CSAS portal requires an explicit lock action. Saved-but-unlocked choices are not processed during allotment; they are only auto-locked when the Phase 2 window closes.
• Skipping safe backup choices — students who only fill top-tier choices risk going unallotted in early rounds if competitive closing scores are higher than expected this year.
• Using Class 12 percentage instead of CUET scores to compare — DU CSAS uses CUET UG NTA aggregate scores exclusively. Class 12 board percentage plays no role in the merit calculation.
• Waiting until the last day to fill choices — portal traffic spikes near deadlines. Complete and lock your choices at least two days before the Phase 2 window closes to avoid losing your list to a timeout or technical error.
