DU CSAS Phase 2 2026: Registration Open — Preference Filling Strategy, Cutoffs and Everything You Must Do Before the Deadline

DU CSAS Phase 2 2026 is the most consequential stage of the Delhi University undergraduate admission process for this academic year. With the CUET UG 2026 result declared on June 23 and the CSAS portal now active for Phase 2 registration and preference filling, every candidate who wants a seat in Delhi University’s undergraduate programmes must act with precision and urgency. Missing the Phase 2 window or filling preferences incorrectly can cost you a seat at a college that your CUET score legitimately qualifies you for.

This guide covers every critical step in the Phase 2 process — registration, preference filling strategy, understanding allocation rounds, and the specific decisions that determine whether you get your best available outcome.

What Phase 2 Is and Why It Is the Most Important Stage

The CSAS admission process operates in three phases. Phase 1 covered registration and programme application — the stage where candidates declared which undergraduate programmes they wished to be considered for based on their CUET subject performance and each programme’s eligibility requirements. Phase 2 is the preference filling stage, where candidates rank their college-course combinations in order of priority, from most preferred to least preferred. Phase 3 is the seat allocation stage, where the CSAS algorithm processes all preferences against CUET scores to produce allocation results across multiple rounds.

The preference filling that happens in Phase 2 is not merely a formality. The order in which you fill your programme-college preferences directly determines the outcome of the algorithmic allocation. Two candidates with identical CUET scores can receive dramatically different allocations based entirely on how intelligently they filled their Phase 2 preferences.

Phase 2 Registration — What You Must Complete on the Portal

Before filling preferences, ensure your Phase 2 registration is confirmed on the CSAS portal at the official DU admissions website. The registration requires:

Your CUET UG 2026 Application Number and the Date of Birth used during CUET registration. Your mobile number that was registered with CUET — all OTP verifications during CSAS use this number. Your Class 12 marksheet and certificate details for basic eligibility confirmation. Your category certificate details if you are applying under SC, ST, OBC-NCL, EWS, or PwBD reservation.

Check that your Phase 1 programme applications are correctly showing under your login. If any programme you applied for in Phase 1 appears as ineligible or is missing, contact the DU admission helpline immediately — the deadline for correction is strictly enforced.

The Five Strategic Principles of Preference Filling That Every Candidate Must Follow

Principle 1: List Every Available Preference Slot

The CSAS system allows candidates to fill a large number of programme-college combinations as ranked preferences. Many candidates fill only ten to twenty combinations because they cannot imagine getting certain seats or because they assume certain colleges are too competitive. This is a strategic error.

Fill every available slot — from your most ambitious preference at the top to your most accessible but still acceptable preference at the bottom. The algorithm works down your list only after failing to allocate you to a higher preference. An empty slot at position 47 means you have given up an allocation opportunity that could have been your safety net. A filled slot at position 47 with a programme-college combination you would genuinely accept provides protection that costs you nothing.

Principle 2: Rank by Programme First, Then College Within Programme

The most consequential preference filling decision is whether you rank by college prestige or by programme alignment with your career goals. The evidence across CUET admission cycles consistently shows that students who rank by programme-career alignment report higher satisfaction with their undergraduate experience and better career outcomes than those who chose a high-prestige college for a programme they were not genuinely interested in.

Establish your preferred programme first. Within that programme, rank colleges from most to least preferred based on faculty quality, placement data, alumni network, and campus environment — not purely on prestige hierarchy.

Principle 3: Understand the Float Option and Use It Strategically

When you receive an allocation in Round 1, you have three choices: accept and freeze, accept and float, or reject. Accept and freeze secures your Round 1 seat permanently. Accept and float holds your Round 1 seat while keeping you in contention for a higher preference in Round 2 — if a better allocation becomes available, you get it automatically; if not, your Round 1 seat remains. Reject removes you from Round 1 allocation and puts you back in the pool for Round 2.

For most candidates, accept and float for any allocation that is genuinely acceptable but not your top preference is the safest strategy. It provides both a secured seat and the possibility of an upgrade. Reject is appropriate only when you are confident your CUET score will secure a significantly better allocation in the next round.

Principle 4: Research the Specific CUET Cutoffs, Not the Old Board Score Cutoffs

The DU admissions system changed completely with CUET. The previous board score cutoffs — which dominated decision-making for a decade — are entirely irrelevant to 2026 admissions. What matters now are the CUET score cutoffs from 2024 and 2025, the first two CUET-based admission cycles.

General category students need 750 to 850 marks to get admission in top DU colleges. However, specific programme and college combinations vary significantly. Research the previous year cutoffs for every programme-college combination you are considering, available through DU’s official admission data publications and education platforms. Finology Recipe

Adjust for 2026 competition levels — an increase in the number of high-scoring candidates this year compared to 2025 may push certain cutoffs upward. Build a buffer of 30–50 marks below a cutoff when deciding whether to include a programme-college combination as a preference.

Principle 5: Do Not Apply for a Programme Without Verifying CUET Subject Eligibility

Different DU programmes require different CUET domain subject combinations. Applying for a programme without having appeared in its required CUET subjects renders your application automatically ineligible for that programme, regardless of your overall CUET score. Verify the specific subject requirements for every programme-college combination you include as a preference before finalising your list.

Programme-Wise Guidance for Phase 2 Preference Filling

For B.Com Hons. Aspirants:

B.Com Hons. is the most competitive commerce programme in the DU system, with cutoffs at SRCC, Hansraj, and Ramjas among the highest in any DU programme. Candidates with CUET scores above 900 in commerce subjects should list SRCC and top-five B.Com Hons. colleges as their first five preferences. Candidates with scores between 800 and 900 should list second-tier colleges like Dyal Singh, Kirori Mal, and Aurobindo in their upper preferences and ensure adequate lower preferences for colleges with more accessible cutoffs.

For B.Sc. Hons. (Science Programmes) Aspirants:

Science programme cutoffs are generally 50–100 marks lower than equivalent commerce programmes at the same college. B.Sc. Computer Science at Hansraj, Ramjas, and Kirori Mal remains highly competitive. B.Sc. Physics, Chemistry, and Mathematics at mid-tier DU colleges have more accessible cutoff ranges.

For BA Hons. (Humanities Aspirants):

BA Hons. English, History, Political Science, and Psychology at Miranda House, Lady Shri Ram, and Hindu College carry the highest humanities cutoffs. The BA Programme — DU’s multi-disciplinary option — offers broader college access at somewhat lower score requirements and is worth including in Phase 2 preferences as an anchor option.

After You Submit Your Preferences — The Allocation Round Schedule

Following Phase 2 preference submission, DU will conduct allocation rounds. Round 1 allocations are processed and published on the CSAS portal. Candidates must respond to their Round 1 allocation within the specified window — accept and freeze, accept and float, or reject. Round 2 allocations follow for those who floated or rejected.

Monitor the official DU admissions website and your registered email daily during the allocation period. Missing the response window for any allocation round forfeits that round’s result — a serious and irreversible consequence.

Fee payment is required to confirm every allocation before the deadline. No allocation is secured without the simultaneous fee payment.
