DU CSAS 2026 admission through CUET is now open. The Delhi University Common Seat Allocation System (CSAS) UG portal went live on 27 June 2026 at ugadmission.uod.ac.in, just days after the National Testing Agency declared the CUET UG 2026 result on 23 June 2026. If you appeared in CUET UG and want a seat in any of DU’s 91 colleges, registering on the CSAS portal is mandatory — your CUET scorecard alone does not secure admission. This guide walks you through the full CSAS process, Phase 1 and Phase 2 steps, fees, and the preference-filling strategy that decides which college you actually get.
DU CSAS 2026: What Just Happened
The admission window opened immediately after a fast-moving CUET cycle. The CUET UG 2026 exam was conducted between 11–31 May and 6–7 June 2026 in computer-based mode for over 15.6 lakh registered candidates. NTA released the final answer key on 21 June 2026 (dropping 7 questions across shifts) and declared results on 23 June 2026. With scorecards in hand, lakhs of students are now converging on the DU CSAS portal — and Delhi University allocates over 70,000 UG seats across 91 colleges entirely on your normalised CUET UG percentile and your locked preferences.
One point trips up every batch: CUET counselling is not centralised. NTA’s job ends at result declaration. Every university — DU, BHU, Allahabad, Hyderabad and 250+ others — runs its own admission process. So you must register separately on each university’s portal where you want a seat. For DU, that portal is CSAS.
DU CSAS 2026 Process: The Three Phases
The CSAS journey runs in three sequential phases. You cannot skip ahead — each phase unlocks the next.
- Phase 1 — Registration: Log in with your CUET credentials, fill personal and academic details, upload documents, and pay the CSAS fee. This phase is live now (opened 27 June 2026).
- Phase 2 — Preference Filling: Select and rank college + programme combinations. This is where your CUET score meets the merit list. A preference-change window is expected in the second week of August 2026.
- Phase 3 — Seat Allotment: DU runs allotment rounds, followed by seat acceptance, online fee payment, and physical document verification at the college.
Phase 1 Registration: Fees and Documents
The Phase 1 (CSAS Part 1) application fee is ₹250 for General, OBC-NCL and EWS candidates and ₹100 for SC, ST and PwBD candidates. Keep these ready before you start so the form does not time out:
- CUET UG 2026 application number and scorecard
- Class 10 and Class 12 marksheets / certificates
- Category certificate (if applicable) — OBC-NCL, EWS, SC, ST, PwBD
- A valid photo ID, passport-size photo and signature
- ECA / Sports certificates, if you are applying through those supernumerary quotas
Not sure how your raw marks translate into a competitive percentile? Run them through our CUET Score Calculator & Percentile Predictor before you lock preferences — knowing your realistic band keeps your choice list grounded.
Phase 2: How to Fill Preferences Without Losing Your Dream College
Phase 2 choice filling opens only after results, which means it is active in this very cycle. This is the single most decision-heavy step, and most lost seats trace back to a weak preference list. Three rules:
- Add every combination you would accept — including safe backups. DU allots round-wise; an empty backup slot can mean no seat at all.
- Order by genuine preference, not by guesswork. Put your true first choice at the top even if it feels ambitious. The algorithm protects your higher preferences automatically.
- Do not chase only “famous” colleges. A strong programme at a slightly lower-ranked college often beats a weak fit at a top one.
To map which colleges your percentile realistically reaches, study our guide to the Top CUET Universities 2026 and use the CUET Subject Combination Advisor to confirm your subject eligibility for each programme before you lock it.
Common CSAS Mistakes to Avoid
- Treating the CUET scorecard as an admission letter. It is not — no CSAS registration, no seat.
- Filling too few preferences. Short lists are the number-one cause of missing allotment.
- Mismatched subjects. Some DU programmes require specific CUET subjects; an ineligible combination is rejected at verification.
- Waiting till the deadline. Portal load spikes near closing dates — register early in Phase 1.
Planning Ahead for CUET 2027
If you are a Class 11 or 12 student watching this cycle unfold, the lesson is clear: a strong CUET percentile is the only currency in CSAS. Build it early with structured practice on our CUET Mock Tests and full subject coverage through the All-Access Pass. The students who breeze through counselling are the ones who treated the exam, not the form, as the real battle.
