CSAS 2026 — Where Are We Now?
Delhi University's admission follows a 3-phase CSAS process. Phase 1 (Registration) is complete. Phase 2 (Preference Filling) is now LIVE. Phase 3 (Seat Allocation) begins with the first allocation list on July 16.
What is CSAS Phase 2? — Subject Mapping & Preference Filling Explained
Phase 2 is the most critical step in the DU admission process. It has two main components that determine which seat you get allotted:
📎 What is Subject Mapping?
Subject mapping is a mandatory step where you link each Class 12 subject with the corresponding CUET UG 2026 test paper you appeared for. This linkage determines which programmes you become eligible to apply for.
• You must have appeared in CUET in subjects identical or closely related (≥50% syllabus match) to those passed in Class 12.
• General Test cannot be used for subject mapping — it is a separate eligibility component.
• The university's decision on subject equivalence is final.
• Incorrect mapping will make you ineligible for programmes — double-check before saving.
📋 What is Preference Filling?
After subject mapping, the portal automatically shows all programmes you are eligible for. You then create a ranked list of Programme + College combinations (e.g., "B.A. (Hons.) English at Hindu College" is one preference). The order of preferences directly determines seat allocation — your most-desired choice should be at the top.

Follow these steps carefully to complete your CSAS Phase 2 process:
Simulated Ranks — What Are They & How to Use Them
On July 12, 2026 at 5:00 PM, Delhi University will release simulated ranks — a feature unique to the CSAS process. Here's what you need to know:
| Aspect | Details |
|---|---|
| What Are They? | Tentative, mock ranks based on your CUET scores and the preferences submitted by all candidates |
| Purpose | To give you an approximate idea of where you stand relative to other applicants for each programme-college combination |
| Release Date | July 12, 2026, 5:00 PM |
| Are They Final? | No. Simulated ranks are indicative only. Final ranks depend on everyone's revised preferences after the change window |
| What to Do After? | Use the preference change window (July 12–13) to add, delete, or reorder preferences based on your simulated rank position |
| Common Mistake | Treating simulated ranks as guaranteed allocations. They are not. Always keep a mix of aspirational and safe choices |

5 Expert Strategies for Filling Preferences Like a Pro
Your preference order directly determines your seat allocation. Follow these strategic tips to maximize your chances:
| # | Strategy | Why It Works |
|---|---|---|
| 1 | Dream Big at the Top — Place your absolute dream Programme + College at Rank 1, even if your score seems borderline | Cutoffs fluctuate every year. If you don't list it, you have zero chance. If you do, you might be pleasantly surprised. |
| 2 | Fill Maximum Preferences — Add every eligible combination, even those you consider "backup" | More preferences = more chances of allocation in some round. An unfilled preference is a wasted opportunity. |
| 3 | Mix Aspirational + Safe — Blend top-tier colleges with mid-range and safe options throughout your list | Ensures you don't end up without any seat if competition is fierce for top choices. |
| 4 | Research Past Trends — Check previous year's CUET score ranges for various programme-college pairs | Historical data helps you realistically position your preferences and avoid wasting top slots on impossible matches. |
| 5 | Use the Simulated Ranks Wisely — Don't panic-reorder your entire list based on mock ranks | Simulated ranks change after the preference change window. Make targeted adjustments, not wholesale reshuffles. |
After Allocation — Freeze vs Upgrade Decision
Once you are allocated a seat in Round 1 (July 16) and pay the admission fee, you must choose one of these two options for subsequent allocation rounds:
• If allotted your 1st preference, "Upgrade" is typically not available — you already got your top choice.
• If your simulated rank was close to a higher choice, choosing "Upgrade" is worth the attempt.
• Freezing early gives you peace of mind but closes the door on potentially better options.
• The upgrade is risk-free — if not upgraded, your current seat stays intact.
Round 1 Allocation — What Happens After July 16?
When the first allocation list drops on July 16 at 5:00 PM, here's the exact sequence of actions you must follow:
Documents Required for College Verification
Keep these documents ready for upload during the college verification process (July 16–20):
- CUET UG 2026 Scorecard — Downloaded from the NTA CUET portal
- Class 12 Marksheet — Board result with subjects and marks/grades
- Class 10 Marksheet — Date of Birth proof
- Passport-Size Photograph — Recent, white background, JPEG format
- Scanned Signature — Clear, JPEG format
- Category Certificate — SC/ST/OBC-NCL/EWS (if applicable)
- PwBD Certificate — Disability certificate from competent authority (if applicable)
- Migration Certificate — From the board of examination
- Aadhaar Card / Government Photo ID — For identity verification
- Character Certificate — Issued by the school or previous institution
- Sports / ECA Certificates — For supernumerary quota applicants
Common Mistakes to Avoid in Phase 2
| ❌ Mistake | ✅ What to Do Instead |
|---|---|
| Filling too few preferences | Fill every eligible Programme + College combination. More options = better chances. |
| Wrong subject mapping | Cross-check Class 12 subjects with CUET papers carefully. Refer to DU's Bulletin of Information for equivalence rules. |
| Not saving preferences | Click "Save" after every modification. Unsaved preferences are lost and not considered for allocation. |
| Panicking after simulated ranks | Simulated ranks are tentative. Make targeted adjustments, not wholesale reshuffles. Keep dream choices. |
| Ignoring the preference change window | This 24-hour window (July 12–13) is your last chance to modify preferences. Don't miss it. |
| Missing seat acceptance deadline | Accept your seat by July 18 and pay fees by July 21. Late acceptance = seat forfeited. |
| Not keeping backup documents ready | Scan and organize all required documents now. College verification runs July 16–20 — time is tight. |
| Confusing Freeze with Upgrade | "Freeze" = final admission; "Upgrade" = try for higher preference (risk-free). Understand the difference before choosing. |

Frequently Asked Questions (FAQs)
When does DU CSAS Phase 2 start and end?
CSAS Phase 2 started on July 3, 2026, and the deadline for preference filling is July 11, 2026, at 11:59 PM. A correction window is available from July 10 (10 AM) to July 11 (11:59 PM). After simulated ranks on July 12, a final preference change window runs until July 13 at 4:59 PM.
What is subject mapping and why is it important?
Subject mapping is a mandatory step where you link your Class 12 subjects with the corresponding CUET UG 2026 test papers. This determines which programmes you are eligible to apply for. Incorrect mapping can make you ineligible for desired programmes. Subjects must match identically or have at least 50% syllabus overlap.
When is the first DU CSAS allocation list for 2026?
The first CSAS allocation list (Round 1) will be published on July 16, 2026, at 5:00 PM on the official portal admission.uod.ac.in. Seat acceptance runs from July 16–18, college verification from July 16–20, and fee payment deadline is July 21.
What are simulated ranks and how should I use them?
Simulated ranks are tentative, mock ranks released on July 12 at 5 PM. They give you an approximate idea of your standing for each preference but are NOT final. Use them to make targeted adjustments to your preference list during the change window (July 12–13). Don't panic-delete your dream choices based solely on mock ranks.
How many preferences can I fill?
There is no upper limit. You can add as many Programme + College combinations as you are eligible for. It is strongly recommended to fill as many preferences as possible to maximize your chances of getting a seat in any allocation round.
What is the difference between Freeze and Upgrade?
Freeze: You confirm your admission to the allotted seat and will NOT be considered for higher preferences in later rounds. Upgrade: You wish to try for a higher-ranked preference. If upgraded, your current seat is auto-cancelled; if NOT upgraded, your current seat remains safe. Upgrade is risk-free.
Can I change my preferences after the July 11 deadline?
Yes, but only during the preference change window after simulated ranks are released — from July 12 (5 PM) to July 13 (4:59 PM). You can add, delete, or reorder preferences during this 24-hour window. After it closes, preferences are permanently locked.
What if I'm not allotted any seat in Round 1?
If you don't get a seat in the first allocation, don't worry. Your preferences automatically carry forward to subsequent allocation rounds. Seats vacated by candidates who don't accept, don't pay fees, or choose "Upgrade" are redistributed in later rounds.
I haven't completed Phase 1 yet. Can I still participate in Phase 2?
Phase 1 registration is a prerequisite for Phase 2. If you haven't registered yet, complete Phase 1 immediately on ugadmission.uod.ac.in. Without Phase 1 completion (including fee payment), you cannot access the preference filling portal. Read our complete DU CSAS Phase 1 Registration Guide for step-by-step instructions.
What is the seat acceptance and fee payment deadline for Round 1?
For Round 1: Seat acceptance deadline is July 18, 2026. College verification runs until July 20. The last date for online fee payment is July 21, 2026. Missing any deadline forfeits your allocated seat.
Does the preference order really matter?
Absolutely yes. The CSAS algorithm allocates seats strictly based on your preference order combined with your CUET score and category. If you qualify for multiple allocations, you get the one ranked highest in your preference list. Always put your most desired option at Rank 1.
Can I use the General Test score for subject mapping?
No. The General Test cannot be used for subject mapping. It is treated as a separate component for certain programme eligibility requirements. Only domain-specific CUET test papers can be mapped to Class 12 subjects.
