What Is DU Phase 2 Admission (CSAS-UG 2026)? 

Delhi University conducts all undergraduate admissions through the Common Seat Allocation System (CSAS-UG), a centralised, CUET-score-based online portal. The process is divided into two main phases: 

• Phase 1: Candidate registration and payment of the registration fee (began June 26, 2026) 
• Phase 2: Subject mapping, course and college preference filling (began July 3, 2026) 

Only candidates who have completed Phase 1 are eligible to proceed to DU Phase 2 registration. Admission to 73 undergraduate programmes and 150 BA Programme combinations across DU's colleges will be conducted through CSAS-UG based on CUET UG 2026 scores. 

DU Phase 2 Admission 2026: Complete Schedule 

Here is the detailed DU CSAS UG 2026 admission timeline for Phase 2 and seat allocation: 

Delhi University will publish the first CSAS seat allocation list on July 16, 2026, at 5 PM. The second allocation list will follow at 12 noon on July 25, with seat acceptance due by July 26, college verification by July 27, and the fee payment deadline set for July 28.

Who Can Apply for DU CSAS Phase 2? 

Only candidates who have already registered and paid the fee in Phase 1 are eligible for Phase 2. DU has made it clear that candidates can participate in Phase II only after completing Phase I. If you missed Phase 1, check the official portal for any extension notices before the July 11 deadline, as both phases close simultaneously. 

Step-by-Step Guide: How to Complete DU Phase 2 Registration 2026 

Follow these steps to complete your DU CSAS Phase 2 subject mapping and preference filling: 

Step 1: Log In to the CSAS Portal 

Visit admission.uod.ac.in and log in using your CUET UG 2026 application number and password. 

Step 2: Map Your CUET Subjects with Class 12 Subjects 

Candidates need to map the subjects they studied in Class 12 with the subjects they appeared for in CUET UG 2026. This subject-mapping step is mandatory and determines which programmes you are eligible for, so it must be done carefully. 

Important: DU has stated that candidates should have appeared in CUET for the same or closely related subjects studied in Class XII, as required under the programme-specific eligibility criteria. Mismatched subject mapping can make you ineligible for certain programmes, so always cross-check with the official DU UG Bulletin of Information before proceeding. 

Step 3: Select Preferred Courses and Colleges 

Candidates must select their preferred undergraduate courses and colleges based on the eligibility criteria and arrange their programme-college combinations in order of preference. 

Step 4: Save and Lock Preferences 

Students can choose as many course and college combinations as they want; however, only the preferences saved before the deadline will be considered for seat allocation. It is strongly recommended not to wait until the last day, as portal traffic tends to spike close to deadlines. 

Step 5: Use the Correction Window if Needed 

A correction window is open from July 10 to July 11, allowing candidates to fix errors in registration details before the final lock. 

Step 6: Track Simulated Ranks 

Simulated ranks will be released on July 12 (5 PM), giving candidates an estimate of their likely allocation based on current preferences — useful for making last-minute adjustments during the preference change window (July 12-13). 

DU Seat Allocation Process: What Happens After Preference Filling? 

Once Phase 2 closes on July 11, DU will process preferences and CUET scores to generate the first CSAS allocation list on July 16. Here's what candidates need to do at each stage: 

1. Accept the allotted seat (or choose to upgrade in later rounds, if eligible) 
2. Complete college-level document verification within the specified window 
3. Pay the admission fee before the round-specific deadline to confirm the seat 

Candidates who are not satisfied with their Round 1 allocation can wait for the second allocation list on July 25 to try for an upgrade, based on how they have arranged their preferences. 

Common Mistakes to Avoid During DU Phase 2 Registration 

• Incorrect subject mapping - always match CUET papers with Class 12 subjects as per programme eligibility norms 
• Careless preference ordering - the sequence of your college-programme preferences directly affects your final allotment 
• Missing the preference-lock deadline - no edits are possible once the window closes 
• Ignoring the CSAS dashboard -all official communication from DU is sent through the dashboard and registered email, not SMS 
• Delaying fee payment- failing to pay within the deadline after allotment can lead to forfeiture of the seat
