DU CSAS Phase 2 is the preference-filling stage of Delhi University undergraduate admission, where CUET UG qualified students map their Class 12 subjects and rank college-programme choices in order.
Admission to all regular UG programmes at Delhi University runs solely on CUET UG scores through the Common Seat Allocation System, or CSAS (Delhi University admission portal). Phase 2 is the decisive stage because the preferences you save here directly shape the seat you are offered in the allocation list, as stated on admission.uod.ac.in.
Key Takeaways
- Phase 2 needs completed Phase 1 registration first, then subject mapping and a ranked list of college-programme preferences.
- Preferences auto-lock at the deadline, so save more choices rather than fewer to protect your chances.
- Order preferences by genuine priority, because the system offers your highest-ranked eligible combination that your CUET score can reach.
CampusFeed Take
The single biggest mistake students make in DU CSAS Phase 2 is filling too few preferences to feel “safe.” The logic runs the other way. Every college-programme pairing is a separate rankable choice, and the system simply offers your highest-ranked option your score can reach, so a long, honestly-ordered list only helps you. The students who should watch most closely are those with mid-band CUET scores, where one extra safe preference at the bottom of the list can be the difference between a DU seat and none. Rank by true preference, add depth below it, and let the algorithm do the rest. By Harshvardhan Jain.
What is DU CSAS Phase 2?
DU CSAS Phase 2 is the second stage of Delhi University’s centralised admission process, where a candidate maps subjects and submits ranked college-programme preferences. It follows Phase 1, the one-time registration stage. Only students who completed Phase 1 can take part in Phase 2. The stage involves two core actions on the portal: mapping your Class 12 board subjects to the CUET UG papers you attempted, then building a prioritised list of programme-and-college combinations.
DU CSAS Phase 2 Key Steps and Rules
DU CSAS Phase 2 follows a fixed sequence of steps on the official portal, each with its own rule. The table below sets out the flow every candidate must complete.
| Step | What Happens | Key Rule |
|---|---|---|
| Phase 1 check | Log in with existing credentials | Phase 1 registration is mandatory before Phase 2 |
| Subject mapping | Link Class 12 subjects to CUET UG papers | Subjects must match, or meet the eligibility overlap rule |
| Preference filling | Rank college-programme combinations | No limit on the number of preferences you can add |
| Auto-lock | Window closes on the deadline | Preferences lock automatically, no late edits |
| Simulated ranks | Tentative rank shown after the window | Based on scores and preferences submitted |
| Reorder window | Short window to re-sequence choices | Reordering only, no adding or deleting preferences |
The most important data point here is the reorder rule. After simulated ranks appear, you can only change the order of your existing preferences, so anything you forgot to add earlier cannot be added later.
About Delhi University
Delhi University is a central university established in 1922 and funded through the University Grants Commission, or UGC. It admits undergraduate students across dozens of programmes and 91 constituent colleges through the CUET-based CSAS process each year. It ranks among India’s most applied-to central universities, drawing lakhs of CUET UG candidates for its UG seats every admission cycle, as listed on the official admission portal.
Why is subject mapping so important?
Subject mapping in DU CSAS Phase 2 decides which programmes you are eligible to select, so an error here can quietly block your preferred course. During mapping, you match each Class 12 subject to the CUET UG paper you sat. Delhi University then shows only the programmes your subject combination qualifies you for, and displays your programme-specific merit score. Programme eligibility and subject requirements are set by the university, so review each mapping carefully against the eligibility conditions published on the DU admission portal before you lock preferences.
What This Means For You
If you are a student
Complete Phase 1 first, then treat mapping as carefully as the exam itself, because a wrong subject match can remove a course you wanted. Fill many honest preferences, not few. Rank them by real priority, since the system offers your highest-ranked reachable option. Keep checking admission.uod.ac.in for each window’s exact timing.
If you are a parent
Your main job is calm support and deadline tracking. Preferences auto-lock, so help your child finish well before the closing time rather than at the last hour. Encourage a long preference list built on interest and eligibility, not fear. Avoid pressuring a single “dream college,” because breadth of choice protects the final outcome.
If you are a school principal or teacher
A short session on subject mapping and preference strategy helps your Class 12 batch avoid common errors. Many students under-fill preferences or mismatch subjects. Point them to the official portal for exact dates and eligibility, and remind them that reordering after simulated ranks cannot add missed choices.

What Is Next
Once preferences lock and simulated ranks appear, use the reorder window wisely, then wait for the allocation list. After a seat is allotted, you accept it, complete document verification, and pay the fee within the stated deadlines. Keep every document scanned and ready. Which college-programme combination will you place at the very top of your list?
