The registration window for CUET UG 2026 has opened, and millions of students across India are preparing to submit their applications. If you plan to pursue an undergraduate programme at central, state, or participating universities, this exam is your gateway. But here's the catch: one small mistake in your application form can lead to rejection.
The National Testing Agency (NTA) has set 30 January 2026 as the last date to apply. You can only fill the form on the official website cuet.nta.nic.in. While the process seems simple, many students make errors that cost them their chance at admission. Let me walk you through the six most common mistakes and how you can avoid them.
Personal Details: Get Them Right the First Time
Your name, date of birth, and parents' names must match exactly with your official documents. I've seen students type their names in different formats or miss a middle name. This creates problems during document verification later. Check your Class 10 and 12 certificates before entering any information. Even a small spelling difference can raise red flags.
Contact Information Matters More Than You Think
Many students forget to update their mobile numbers or use email addresses they rarely check. This is a big mistake. The NTA sends all important notifications through these channels. Your admit card, exam centre details, and results will arrive via SMS and email. Make sure you have active access to both your registered mobile number and email account throughout the admission process.
Category Certificate: Don't Skip This Step
If you belong to a reserved category, you need to upload the correct certificate. Students often forget this step or upload documents that don't meet the required specifications. Without a valid category certificate, you cannot claim reservation benefits. This could affect your chances of getting into your preferred college, especially in competitive courses.
Subject Mapping Can Make or Break Your Application
This is where many students go wrong. You can choose up to five subject tests, but they must align with your chosen course. For example, if you want to study Economics, you need to select the right combination of subjects that universities require for this course. Picking wrong subject test codes will make you ineligible for certain programmes, even if you score well in the exam.
Each university has specific subject requirements. Before filling the form, visit the websites of universities you want to apply to. Check their eligibility criteria and note down the exact subjects they need. Keep this information handy while filling your CUET form.
Photo and Signature Quality: The Technical Requirement
Blurry photos and unclear signatures are common reasons for application rejection. Your photograph should be recent, with a plain background. Your signature should be done on white paper with a black or blue pen. Scan both documents in the exact format and size mentioned in the guidelines. Don't rush through this step. If your photo or signature doesn't meet the standards, your entire application gets rejected.
The Last Day Rush: A Recipe for Disaster
Thousands of students wait until the final day to submit their forms. This creates heavy traffic on the website. Servers often slow down or crash on the last day. You might face payment gateway failures or form submission errors. Why take this risk? Complete your application at least a week before the deadline. This gives you time to fix any problems that might come up.
Understanding CUET UG 2026
The Common University Entrance Test for Undergraduates is a national level entrance exam. Your CUET score helps you get admission to various undergraduate courses like BA, BSc, BCom, and BBA at central and participating universities. The exam happens in computer-based mode at centres across India and abroad. You can take the test in any of the 13 available languages.
Step by Step Application Process
Start by visiting cuet.nta.nic.in and clicking on 'New Registration'. Enter your basic details like name, date of birth, mobile number, and email to create your login credentials. You will receive OTPs on both your mobile and email. Enter these codes to verify your contact information.
Next, fill in your personal details, educational qualifications, address, and category information. Now comes the document upload section. Keep these ready before you start:
- Class 10 and 12 marksheets
- Passport size photograph
- Signature sample
- Identity proof (Aadhaar card or driving licence)
- Category certificate or disability certificate if applicable
After uploading documents, select your subjects carefully. Remember, you can choose up to five subject tests. Make sure they match the requirements of courses you want to pursue. Then proceed to payment. You can pay through net banking, UPI, or debit and credit cards. Once payment is successful, submit your form and download the confirmation page. Keep this document safe.
Quick Tips for a Smooth Application
Read the official information bulletin carefully before starting your application. It contains all the important instructions and guidelines. Scan and save all your documents in advance. This saves time during the actual form filling process.
When choosing your exam city, pick locations close to where you live. This makes travel easier on exam day. After submitting your form, save multiple copies of your confirmation page and payment receipt. You might need them later.
Some students panic about subject selection. Take your time with this step. Make a list of universities and courses you want. Check what subjects each course needs. Then match your subject selection accordingly. If you're confused, ask your school counsellor or teachers for guidance.
Why These Details Matter
You might wonder why such small things can cause big problems. The CUET exam has lakhs of applicants. The system processes applications automatically. If your details don't match the format or requirements, the computer flags your application. There's no human checking each form initially. By the time you realise there's a problem, the correction window might have closed.
Your CUET application is not just a form. It's your entry ticket to your dream college and course. Taking extra care now saves you from disappointment later. Double check every field before moving to the next section. Ask someone else to review your filled form before final submission. A fresh pair of eyes can catch errors you might miss.
The registration process might seem long, but it's worth doing properly. You have worked hard to reach this point. Don't let a silly mistake in the application form stop you from getting the college education you deserve. Fill your form carefully, submit it early, and then focus your energy on exam preparation. Good luck with your CUET journey.
