DU CSAS Preference is filled in a very systematic and strategic manner to maximise your chances of getting the best possible college and course in Delhi University.

Delhi University admissions are completely preference-based and not conducted through traditional counselling. Seats are automatically allotted based on your CUET normalized score, preference order, category, and seat availability.

Preference Filling for DU UG Admissions is done on the official DU CSAS Portal https://ugadmission.uod.ac.in/

Why Preference Filling is Important in DU CSAS?

The preference list is very important for final seat allotment. Even a small mistake while arranging preferences can lead to missing out on a preferred college or course. That is why students should fill their preferences carefully and in the right order to improve their chances of getting admission to their dream college.

Important Note:

  • Students cannot change the order of their preferences.
  • But they can get upgraded to a higher preference (better college) in later rounds if someone with a higher score leaves that seat.

DU CSAS Preference Filling Process Explained

How to Fill DU CSAS Preferences 2026?

Step 1: Visit the Official DU CSAS Portal

  • Go to the official Delhi University admission portal and log in using your CUET Application Number and password.

Step 2: Complete Your Profile Details

Before filling in preferences, complete all important details carefully, including:

  • Personal information
  • Category certificate upload (if applicable)
  • Required documents
  • Subject mapping

Step 3: Open the Preference Filling Section

After the declaration of CUET results, the Delhi University opens CSAS Phase II for preference filling. This is the most important phase where Students can:

  • Search courses using the search bar
  • Add your preferred colleges and courses together
  • Arrange them in your order of preference (most preferred at the top)
  • Then add your next preferred options below it.
  • Keep comparatively achievable colleges lower in the preference list.

Students can add up to 200 preferences (recommended to fill the maximum).

Step 4: Step 5: Save & Lock Your Preferences

  • After arranging your college and course preferences, click on “Save” to update the list. Students can edit their preference order multiple times before the deadline. Once satisfied, they must click on “Lock Preferences” to submit the final list.

After the last date, preferences get automatically locked, and no further changes are allowed. Students should also keep a screenshot or a PDF copy of the final preference list for safety.

Important Note:

  • Students should check the preference order carefully before locking because once the preferences are locked, the order cannot be changed later.
  • The DU CSAS preference filling window is usually very short, with students getting only around 5- 7 days to submit their preferences before the portal auto-locks.
  • Subject mapping is very important in CUET-UG. If a student chooses the wrong subjects or subject combination, they may become ineligible for admission to their desired course.

What Happens After Seat Allotment in DU CSAS?

The Freeze and Upgrade options appear after a student gets a seat allotment in any CSAS round of Delhi University admissions. These options become available only after the student accepts the allotted seat and pays the admission fee.

  • Upgrade: Be considered for higher preferences in the next round
  • Freeze: Keep the current seat and stop further upgrades

Even after locking your preferences, the Upgrade option still works during later Delhi University CSAS rounds. Your preference order remains fixed, but DU automatically checks the same list again in every round to see if a better college or course becomes available.

DU CSAS Preferences Filling Important Tips

  • Fill Maximum Preferences

Students should try to add as many college + course combinations as possible, ideally around 150–200 preferences. A larger preference list increases the chances of getting a seat during the Delhi University counselling rounds.

  • Preference Order Matters the Most

The order of preferences is extremely important in DU CSAS counselling. Students should always place their dream college and favourite course at the top of the list, while safer options should be kept lower. DU checks preferences from top to bottom during seat allotment.

  • Decide Between Course vs College Priority

Before filling out preferences, students should decide what matters more to them - a specific course or a specific college. Some students may prefer getting their favourite course, like B.Com (Hons.) or Computer Science, in any good college, while others may prioritize a particular college even if the course is slightly less preferred.

  • Lock Preferences Carefully

Before clicking on “Lock Preferences”, students should carefully check the entire order of the list. Once preferences are locked, the order cannot be changed later.

  • Check Seat Availability

Students should also check the approximate seat matrix before adding preferences. Colleges with fewer seats usually become more competitive during counselling.

  • Use Category Advantage Smartly

Students belonging to EWS, OBC, SC, or ST categories should add more top colleges in their preference list because reserved categories usually get relaxation in cutoff scores during University of Delhi admissions.

  • Check Previous Year Cutoffs

Before finalizing the preference order, students should check the previous year's DU cutoffs to understand which colleges and courses are realistic according to their expected CUET score.

DU CSAS Preference Filling Strategy & Common Mistakes to Avoid

A well-planned preference list can improve your chances of getting the right college and course in Delhi University.

  • Avoid Common Mistakes

Many students lose good opportunities because of small mistakes during CSAS counselling. Students should avoid:

  • Filling preferences from only one stream
  • Keeping the preference list too short
  • Forgetting to lock preferences before the deadline
  • Maintain a Balanced Preference List

Many students make the mistake of adding only top colleges. Instead, students should keep a balanced mix of:

  • Dream colleges
  • Mid-range colleges
  • Safe backup colleges

This strategy gives better admission chances in multiple rounds.

  • Understand Multiple CSAS Rounds

Students who do not get a seat in the first round should not panic. DU conducts multiple counselling rounds, and students can still get upgraded seats later based on their preference order and seat availability.

  • Do Not Leave Empty Gaps

Students should continuously fill preferences without leaving unnecessary gaps. Adding more valid preferences improves the chances of getting a seat in later rounds.

  • Save Your Progress Regularly

While arranging preferences, students should keep clicking on “Save” regularly so that the progress is not lost because of a logout or technical issues.

  • A Smarter Preference Filling Approach

While filling preferences, it is generally better to give importance to your preferred course first rather than focusing only on college names. If courses like Computer Science, Psychology, or B.Com (Hons.) are your main goal, choose the course carefully before comparing colleges.
