Delhi University opens CSAS UG 2026 portal for CUET-qualified students. Check registration dates, eligibility

Introduction

You’ve cleared CUET UG 2026 — that’s a significant achievement. But the race to a Delhi University seat is only halfway done.

The University of Delhi has officially opened the CSAS UG 2026 portal for CUET-qualified candidates, marking the start of one of India’s most competitive undergraduate admission processes. With over 70,000 seats across 91 colleges and nearly 20 lakh students competing, every step you take in this portal matters.

This guide walks you through everything — from important dates and eligibility rules to a step-by-step registration process and smart preference-filling strategies. Whether you’re aiming for SRCC, Miranda House, or Hindu College, this is the complete playbook you need.

What Is the DU CSAS UG 2026 Portal?

CSAS stands for Common Seat Allocation System. It is the University of Delhi’s official, centralised online admission platform, available at ugadmission.uod.ac.in.

Before 2022, students applied to each college separately and chased cut-off lists. The CSAS portal replaced that chaotic process with a single, transparent, merit-driven system based entirely on CUET UG scores.

Through CSAS, you:

• Create your admission profile
• Upload required documents
• Fill in your college and course preferences
• Receive seat allocation results across multiple rounds
• Accept, upgrade, or freeze your allotted seat

There are 79 undergraduate programmes spread across 91 affiliated colleges — from BA (Hons) Economics and BCom (Hons) to BSc (Hons) Mathematics and BMS.

Key fact: Clearing CUET alone does NOT guarantee a DU seat. Registering on the CSAS portal is mandatory. Without CSAS registration, your CUET score carries no weight in the DU admission process.

Important Dates at a Glance

Here is a snapshot of the DU CSAS UG 2026 timeline based on the latest available information:

Note: Phase 2 and subsequent dates are tentative and subject to official updates on admission.uod.ac.in. Always verify directly on the official portal.

Who Is Eligible to Apply?

DU’s eligibility criteria for UG admission 2026 are clear and non-negotiable:

Basic Requirements

• Educational qualification: Must have passed Class 12 or an equivalent examination from a recognised board.
• CUET UG 2026: Appearing in CUET UG 2026 is mandatory for all regular undergraduate programmes (except SOL, NCWEB, and foreign nationals).
• No minimum percentage in Class 12: Admission is based entirely on normalised CUET scores. Board marks carry zero weight (except as a tie-breaker).
• No age limit: There is no upper or lower age bar for DU UG admission, except where required by regulatory bodies (e.g., medical courses under MCI norms).
• Gap year candidates: Fully eligible, provided they appeared in CUET UG 2026.

Critical Rule — Subject Mapping

This is where many candidates go wrong. DU strictly enforces that:

• The CUET domain subject papers you appeared in must correspond to subjects you studied in Class 12.
• For example, if you did not study Mathematics in Class 12, you cannot apply for BSc (Hons) Mathematics at DU.
• If your Class 12 subject has no direct CUET equivalent, you must appear in a closely related subject.

This subject mapping rule is strictly enforced in 2026 — any mismatched combination will be rejected outright.

Programme-Specific Notes

• BMS and BBA-FIA: These management programmes now place higher weightage on the General Test and Mathematics in CUET for 2026. Check the UG Bulletin carefully before applying.
• BA (Hons) via ECA/Sports quota: 50% of CUET score + 50% of performance/certificate score.
• BSc courses: A minimum of 30% in CUET 2026 is required for eligibility.
• SOL and NCWEB programmes: Do not require CUET scores and follow a separate process.

Documents You Need Before Registering

Keep all these documents ready in scanned/digital format before you sit down to register. Interruptions mid-application are a common, avoidable mistake.

•  Class 10 Marksheet and Certificate (for date of birth proof)
•  Class 12 Marksheet and Passing Certificate
•  CUET UG 2026 Scorecard (download from cuet.nta.nic.in)
•  Recent Passport-sized Photograph (note: auto-filled from CUET — non-editable)
•  Signature (also auto-filled from CUET — non-editable)
•  Category Certificate — SC/ST/OBC-NCL/EWS/PwBD (if applicable)
•  Transfer/Migration Certificate from last school attended
•  Government-issued Identity Proof (Aadhaar, Voter ID, or Passport)
•  ECA/Sports certificates (if applying under these quotas)
•  Minority certificate (if applicable)

Important: Details like your name, photo, and signature are auto-fetched from the CUET database and cannot be edited in the CSAS portal. Any discrepancies must be addressed before you register.

Registration Fee Structure

The CSAS registration fee is a one-time, non-refundable payment — separate from the CUET exam fee you already paid to NTA.

Payment is accepted online only — via debit card, credit card, net banking, or UPI. No offline or cash payment is available at any stage.

After seat allotment, you will separately pay the college admission fee (annual DU UG fees typically range from ₹8,000 to ₹30,000 depending on the programme and college).

Step-by-Step Registration Guide

Phase 1: Registration (Currently Open)

Step 1: Visit the official DU CSAS portal at ugadmission.uod.ac.in

Step 2: Click on “New Registration” on the homepage.

Step 3: Enter your CUET UG 2026 Application Number, Roll Number, and Date of Birth exactly as they appear on your CUET documents.

Step 4: The system will auto-fetch your personal and academic details from the NTA CUET database. Carefully verify every field before proceeding — errors here can cause problems later.

Step 5: Upload all required documents in the prescribed format and file size.

Step 6: Set a secure password and save your login credentials.

Step 7: Pay the applicable CSAS registration fee online and confirm payment.

Step 8: Save or print your registration confirmation for reference.

Pro tip: You can — and should — complete Phase 1 right now, even before your CUET result is out. Phase 1 only requires profile creation, document upload, and fee payment. Preference filling only opens after results.

The Three Phases of DU Admission 2026

DU’s CSAS process is structured in three mandatory phases. Missing any deadline means disqualification.

Phase 1 — Registration

Profile creation, personal and academic detail verification, document upload, and fee payment. This phase is currently open.

Phase 2 — Preference Filling

Once CUET UG 2026 results are declared, you log back in and select your college-programme combinations in order of preference. This is the most strategic step.

Key points for Phase 2:

• You can list as many college-programme combinations as you like (as long as you meet the eligibility for each).
• List your most desired choice first — the system automatically considers lower preferences if you don’t qualify for higher ones. Listing a reach college first costs you nothing.
• DU will release Simulated Ranks before the first official list — use these to gauge your position and reorder preferences if needed.
• A Preference Change Window typically opens in the second week of August, giving you one more chance to revise your list.

Phase 3 — Seat Allocation

Seats are allocated across multiple rounds based on your CUET score, preference order, category, and seat availability. After each round, you can:

• Accept (Freeze): Confirm your seat. No further upgradation.
• Upgrade: Hold your current seat while the system tries to push you to a higher-preference option in the next round.
• Reject/Cancel: Cancel with a ₹1,000 non-refundable fee.

In 2025, Round 1 General category cutoffs for top programmes reached as high as 926/1000 — but later rounds saw drops of 10–25 marks, meaning subsequent rounds offer genuine opportunities, not just leftover seats.

Seat Allocation: How It Works

The DU CSAS merit list is generated entirely on normalised CUET UG 2026 scores — board marks have no role. In case of a tie, DU applies this hierarchy:

1. First tiebreaker: Class 12 board marks (best of 3 subjects, then 4, then 5)
2. Second tiebreaker: The older candidate is given priority if tie persists

Once a seat is allotted, you must accept it on the portal within the specified deadline. Non-action results in cancellation, and you lose eligibility for future rounds.

Common Mistakes to Avoid

Even smart students lose seats due to avoidable errors. Watch out for these:

• Wrong subject mapping: Selecting CUET subjects not studied in Class 12 — your application will be rejected.
• Not verifying auto-fetched data: Errors in auto-populated fields can derail your admission later.
• Skipping fee payment: Registration is considered incomplete without confirmed payment.
• Careless preference ordering: The order directly determines your allocation. Think strategically.
• Missing the preference-lock deadline: No changes are possible after the auto-lock. The system doesn’t wait.
• Ignoring your dashboard: All DU communications go through your CSAS dashboard and registered email. Check it daily.
• Assuming CUET score is enough: Without CSAS registration, your score counts for nothing at DU.

Tips to Maximise Your Chances

• Register now in Phase 1 — don’t wait for results. Get it done early.
• List reach colleges first — CSAS won’t penalise you for listing aspirational options high.
• Use Simulated Ranks wisely — they give you a data-driven preview of your chances before official lists.
• Apply across multiple programmes — don’t limit yourself to just one course type. If you’re comfortable with both BA Economics and BCom, list both across colleges.
• Check the UG Bulletin 2026-27 — every programme has specific eligibility quirks. Read them before Phase 2.
• Keep documents ready early — uploading a low-resolution certificate can cause verification issues at the college stage.
• Watch for spot rounds — if you miss the main rounds or want to try for a different seat, DU often runs spot allocation rounds at the end.
