The University of Delhi (DU) has opened a one-time correction window for candidates who have applied for undergraduate admissions for the 2025-26 academic year.

DU UG Admission 2025: Correction Window Now Open - Edit Your CSAS Form by July 11
The correction window is available from July 6 to July 11, 2025, allowing students to make specific changes in their CSAS (Common Seat Allocation System) application form through the official admission portal - admission.uod.ac.in.
This opportunity comes after the completion of Phase 1 registration and is meant to help candidates rectify any errors before moving to Phase 2 of the admission process. Important Dates
Correction Window Opens: July 6, 2025
- Last Date to Edit Application: July 11, 2025 (until 11:59 PM)
- Portal: admission.uod.ac.in
What Can Be Edited?
Students can edit key details such as:
- Academic records (Class 12 subject marks, board details)
- Uploaded certificates and supporting documents
- CUET 2025 application number and score details
This edit option is available only once, so applicants must review the form thoroughly before final submission.
What Cannot Be Changed?
Some critical fields are non-editable, including:
- Candidate's name, gender, and date of birth
- Email address and mobile number used for registration
- Category (General/OBC/SC/ST/EWS)
- Chosen quota or reservation claims (e.g., sports, ECA)
How to Make Corrections
- Go to the official DU admission portal: admission.uod.ac.in
- Log in using your registered email ID and password

Why It Matters

DU authorities have emphasized that no correction requests will be entertained after July 11 under any circumstances.
What Happens After the Correction Window?
- Phase 2 of UG admissions begins on July 8, where candidates can fill and lock their college and course preferences.
