One error, one missed deadline, or one wrong form entry can cost you an entire year. This comprehensive guide about the CSAS Portal for DU Admissions 2025, breaks everything down so you can proceed confidently and error-free.

What Is the CSAS Portal for DU Admissions 2025?

The CSAS portal for DU Admissions 2025 is an online centralised admission system developed by Delhi University for undergraduate admissions via CUET UG. It streamlines the entire process from basic registration and document uploads to course preference filling, simulated ranks, and seat allocation.

CSAS Admission Process: A 3-Phase Breakdown

Phase 1: Registration

In this first phase, candidates are expected to:

• Register with their CUET UG 2025 application number
• Fill in personal and academic details
• Upload required documents (like category certificates, PwBD certificates, etc.)
• Pay the registration fee:
  • ₹250 for General/OBC/EWS categories
  • ₹100 for SC/ST/PwBD

Important Tip: Use official documents for reference. Even minor spelling mismatches between your CUET application and CSAS registration can result in rejection.

Phase 2: Filling Preferences

Once CUET UG 2025 results are announced (expected by late June or early July), students must:

• Select their preferred DU colleges and courses
• Rank them in order of preference

The university provides a Simulated Rank List to help you optimize preferences based on real-time trends and your expected performance.

Key Advice: Always update preferences based on simulated ranks. Do not freeze low-priority choices unless you’re absolutely sure.

Phase 3: Seat Allocation and Admission

Seat allocation will be based on:

• CUET UG scores
• Category
• Order of preferences
• Seat availability

You must:

• Accept the allocated seat
• Upload final documents
• Pay admission fees
• Respond promptly to any college-level queries

Note: Inactivity during this phase is interpreted as withdrawal and may lead to automatic cancellation.

Why This Process Deserves Your Full Attention

Thousands of aspirants face rejection each year not due to low marks but due to avoidable mistakes:

• Incorrect CUET application number
• Missing or invalid documents
• Ignoring the importance of preference order
• Wrong subject mapping

Approach this process strategically. Treat it as a serious step toward your career, not just another form.
