What is the CSAS Portal UG 2025?
The CSAS Portal UG 2025 is the official online gateway for undergraduate admissions to the University of Delhi for the academic year 2025-26.

- Phase III: Allocation-cum-Admission: This is the seat allotment phase, where seats are allocated based on CUET scores, preferences, and availability, followed by document verification and fee payment.
