Quick Overview of Top 10 CUET UG 2026 Common Errors

1. Entering Incorrect Personal Details

One of the greatest errors made in the CUET UG 2026 application form is the incorrect entry of personal information. Details such as your name, date of birth, father's name, and permanent address should match those on your official documents (Class 10 or 12 certificates and ID proof). Even small spelling errors can cause trouble down the road, such as during the verification of documents at universities.

Verified Check: Tip to check all fields and move on to the next section.

2. Misspelled or Inactive Contact Information

Providing an inactive/ wrong mobile number or email ID is a very common mistake. Remember, the National Testing Agency (NTA) sends all important alerts - admit card release, exam schedule, correction window and results through Email/SMS. If you miss these due to incorrect contact info, you may miss important updates.

✔ Tip: Make sure to use an email and number that you frequently check.

3. Uploading Wrong Documents or Bad Images

One of the biggest reasons why so many applications get rejected is due to incorrect document uploads - your photo, signature, or certificates, etc. Common problems include blurry images, wrong file formats (PNG instead of JPG/JPEG or oversize or undersize files and unclear signatures).

✔ Tip: Scan documents clearly and follow the specified size and format instructions.

4. Incorrect Subject Selection

CUET gives candidates the option of opting for more than one subject test according to their selection of courses. This is where students tend to go wrong - picking the wrong test paper codes, or a combination which is not accepted by the university they wish to study. Each university has its own eligibility requirements, and the option of choosing mismatch subjects can impact your admission, every now and then even if you score high in the exam.

Tip: Before filling this section, make a list of the universities and courses that you want to choose, verify the requirements of these subjects, and then choose accordingly.

5. Not Checking CUET UG 2026 Eligibility Criteria

Many aspirants start the process of CUET UG 2026 registration without knowing the eligibility conditions fully. Whether it's educational qualification, age criteria, or subject specific requirements for certain programs, if you miss on any of these, you can be rejected later in the admission process.

✔ Tip: Read the official notification and eligibility criteria carefully before you start filling out the form.

6. Waiting until the Last Minute

Procrastination is one of the common mistakes to commit in CUET application filling. Waiting for the last days may cause the risk of server crash, slow processing, and payment failure due to heavy traffic. This not only stresses the candidates but may result in incomplete or failed submissions.

7. Payment Failures or Errors

The fee payment is an important step in the CUET UG 2026 application form process. Many applicants have experienced payment failures because of slow internet, gateway timeouts or multiple attempts late at night. If the payment doesn't go through successfully, your application will remain incomplete.

Tip: Access a stable internet connection and make payment early in the day. Take a screenshot of successful transactions and download the payment receipt immediately.

8. Choosing an Exam Centre Without Proper Planning

Some of the aspirants choose examination centres far away from their city, or without thinking about travel plans. Though this may not lead to rejection, it may cause unnecessary stress and logistical issues on exam day.

Verified Tip: Try to pick one that is close to your area, or a place that you can easily reach.

9. Not Reviewing Before Final Submittal

Rushing through the application leads to mistakes in the name details, subject codes, or academic score, which go unnoticed. Once the form is submitted, many sections cannot be edited later.

Tips: Once you are done with each of the sections, read it carefully before submitting it.

10. Ignoring the Correction Window

Sometimes after submitting, candidates realise that they've made a mistake. Fortunately, NTA usually opens a correction window - a limited time in which you can make some changes to your form. However, there are many students who fail to take advantage of this window or do not use it effectively, leaving behind errors that could have been fixed.

✔ Tip: Make a note of the correction window dates and correct any mistakes as soon as possible.
