With the CUET UG 2026 exam window running 11–31 May and the DU CSAS UG portal expected to open in June 2026 right after results, this is the calm before the most consequential 45 days of any DU aspirant’s life. There are ~70,000 UG seats on offer across 91 constituent colleges — all allocated purely on CUET UG 2026 scores. This guide unpacks the DU Information Bulletin 2026-27 (released 6 January 2026), the three-phase CSAS process, the subject-mapping landmine that knocked out thousands last year, and a concrete prepare-while-you-wait checklist for the 21 May – 15 June window.

How the CSAS UG Process Works — Three Phases
Phase 1 — Registration
You create your CSAS account, upload personal + academic documents, and pay the registration fee. This phase opens within days of CUET UG result declaration. Critical detail: register on Day 1. Servers crash in the final 48 hours every year.
Phase 2 — Preference Filling
Once your CUET UG scorecard is uploaded, you fill in college × course preferences — every realistic combination, ranked in descending order of desirability. This is the make-or-break phase. A common error: ranking only top colleges. If your score falls 0.5 percentile short of every Hindu/SRCC/St. Stephen’s preference, you go unallocated. Build a 30–50 preference pyramid with realistic safety options.
Phase 3 — Seat Allocation Rounds
DU runs an algorithmic seat-allocation engine. Round 1 → accept/upgrade/withdraw → Round 2 → spot rounds. Each round you can either lock your allocated seat or wait for upgrade. The process completes by August 2026.
Subject-Mapping Rule — The Landmine
DU strictly enforces that your CUET UG papers must match your Class 12 subjects. If you took CUET Mathematics but did not study Maths in Class 12, your CUET Maths score will not count for any DU programme requiring Maths eligibility. This rule eliminated 12% of applicants in 2025. Cross-check your CUET UG paper basket against your Class 12 mark sheet TODAY — before results arrive.
Detailed cases:
- Eco Hons. at SRCC: needs CUET Maths AND Class 12 Maths. CUET English score is mandatory too (40% weight).
- BCom Hons.: needs CUET Accountancy/Business Studies/Maths AND English.
- BA Programme: two CUET domain subjects + English; choose the highest-scoring combination.
- BSc Hons. Physics: CUET Physics + Maths mandatory; both must be in Class 12.
Categories Exempt from CUET UG
Three groups bypass CUET UG:
- School of Open Learning (SOL): separate merit-based portal.
- Non-Collegiate Women’s Education Board (NCWEB): CBSE Class 12 marks-based.
- Foreign Nationals: apply via DU’s International Students Cell.
If you do not fall in these three buckets, CUET UG is non-negotiable.
Prepare-While-You-Wait Checklist (21 May – 15 June)
Use this 25-day buffer between your CUET UG attempt and CSAS UG portal opening to lock everything in.
- Get a high-quality passport photograph (formal, white background) — same image used everywhere.
- Get a clean signature scan (blue ink, white paper, no shadow). Mobile photos crop-edited rarely pass DU’s auto-validator.
- Digitise: Class 10 mark sheet, Class 12 mark sheet, Class 10 certificate (DOB), category certificate.
- Ensure category certificate is in the central government format, dated within the last 12 months for OBC-NCL.
- EWS certificate — must be in DU’s prescribed format on Annexure-I.
- Sports / ECA / KM / CW supplementary certificates — get all attested copies ready.
- Open a fresh Gmail account dedicated to admissions. Do not mix with WhatsApp/Instagram emails.
- Build your preliminary college × course preference spreadsheet using prior-year cut-offs. Use our CUET 2026 Score-to-AIR guide to translate your expected percentile into an AIR band.
- Bookmark admission.uod.ac.in and DU’s @UnivofDelhi on social media — Phase-1 opens with a 48-hour notice.
- Read DU’s full Information Bulletin 2026-27 PDF — every clause matters.
Where Most Aspirants Lose Marks (Procedurally)
- Picking only “dream” colleges in preference filling.
- Forgetting that preference order is locked after round-1 allocation.
- Missing the “upgrade” deadline (it’s typically 36 hours, not days).
- Not knowing that ECA/Sports quotas have a parallel timeline with trial dates.
- Submitting a category certificate older than 12 months.
Beyond DU — Parallel Portals to Watch
DU is not the only show in town. Plan parallel applications:
- BHU: bhuonline.in — CSAS-equivalent runs after CUET UG result.
- JMI: jmicoe.in for non-CUET courses; CUET for the rest.
- Allahabad Central University, AUD, JNUEE-merged programmes, Hyderabad Central University.
Frequently Asked Questions
Q: Will DU release a separate merit list outside CUET UG? No. The 2022 transition is fully complete — every CSAS-eligible seat is CUET-only.
Q: When does the CSAS UG portal open? Expected in June 2026 after CUET UG result. DU has not officially dated Phase 1 yet — bookmark admission.uod.ac.in.
Q: Can I apply if I took CUET in 2025 but not 2026? No — DU requires the current cycle’s CUET UG 2026 score only.
Q: How many programmes can I apply to? Unlimited — pay one consolidated CSAS registration fee, then list every college × course combination during Phase 2.
Q: What is the supernumerary quota? Reserved seats above the regular intake — for ECA/Sports/Kashmiri Migrant/Children of War Widows etc. Apply through parallel forms during Phase 1.
