Getting a good JAMB score is an important step toward gaining admission into a Nigerian university, but it is not always enough. After UTME, many candidates still need to complete a Post-UTME or admission screening process before they can be considered for admission.
Unfortunately, some candidates lose valuable admission opportunities because of simple mistakes made during Post-UTME registration. These mistakes can include entering the wrong personal information, choosing the wrong course, uploading incorrect results, using an inactive email address, missing the registration deadline, or failing to follow the university’s instructions.
Some universities clearly warn that incorrect information submitted during registration can lead to disqualification. For example, the University of Ilorin advises candidates to cross-check their information before final submission, while other institutions state that incorrect information may affect eligibility or result in disqualification.
The good news is that many Post-UTME registration mistakes can be avoided if you slow down and check your information carefully.
Here are the common Post-UTME registration mistakes you should avoid if you want to protect your admission chances.
1. Entering the Wrong JAMB Registration Number
One of the first details required on many Post-UTME portals is your JAMB registration number.
Entering the wrong number can cause problems because the university uses your JAMB details to identify your application and connect it with your UTME record.
A simple typing error can make it difficult for the school to verify your application.
Before submitting your Post-UTME form, compare the JAMB registration number on the university portal with the number on your JAMB documents.
Do not rely on memory.
Keep your JAMB registration slip or result information beside you while completing the form and check every digit before moving to the next stage.
2. Providing Incorrect Personal Information
Your name, date of birth, gender, state of origin and other personal information should be entered carefully.
A mismatch between your JAMB information and the information on your Post-UTME application can raise questions during admission processing.
The Joint Admissions and Matriculation Board (JAMB) has also warned candidates about avoidable registration mistakes, including biodata mismatches. JAMB specifically advised candidates to ensure that necessary corrections are made on the National Identification Management Commission (NIMC) platform before generating their profile code where applicable.
For example, if your name appears differently across your records, do not simply change it randomly on the university portal.
Where an official correction is required, follow the appropriate JAMB or institution procedure.
3. Using Someone Else’s Email Address
Your email address may look like a small detail, but it can become extremely important during admission.
Universities may use email to communicate application updates, examination information, login details, screening instructions and other important notices.
For example, the University of Lagos specifically requires candidates to use a personal and active email address for Post-UTME registration because it is used for communication.
Using your friend’s, parent’s or agent’s email address can create unnecessary problems.
You could miss an important message, lose access to your application information, or depend on another person to receive information meant for you.
Use an email account that you can access regularly and make sure you know the password.
4. Using an Unreliable Phone Number
The same principle applies to your phone number.
If the university sends important information by SMS or requires your phone number for verification, using a number you do not control can put you at a disadvantage.
JAMB’s registration guidance also emphasizes the importance of personal registration information and restricts the use of the same mobile number for multiple candidates.
Use a working phone number that you can keep active throughout the admission process.
Also, avoid losing the SIM card connected to your admission records.
5. Choosing the Wrong Course
Choosing a course without checking the admission requirements can affect your chances of admission.
Some candidates select a course simply because it sounds attractive or because someone told them it is a good course.
That approach can be risky.
Different programmes may have different UTME subject combinations, O’Level requirements, cut-off marks and other conditions.
Before applying for Post-UTME, confirm that you meet the requirements for your chosen programme.
JAMB encourages candidates to consult its Integrated Brochure and Syllabus System (IBASS) for information about approved institutions, programmes and admission requirements.
Do not assume that because you are eligible for the university, you automatically qualify for every course in that university.
6. Ignoring Your O’Level Requirements
Another common Post-UTME registration mistake is entering or uploading O’Level results without checking whether they satisfy the requirements for the chosen course.
Depending on the university and programme, candidates may need specific credits in subjects such as English Language, Mathematics, Biology, Chemistry, Physics or other relevant subjects.
Some institutions accept results from two sittings, while particular programmes or institutions may have different requirements.
For example, the University of Lagos states specific O’Level requirements for its 2026/2027 screening exercise, while other universities publish their own conditions.
Do not copy another candidate’s subject requirements.
Check the requirements for your own institution and course.
7. Entering Your O’Level Grades Incorrectly
If your WAEC, NECO or NABTEB result contains a particular grade, enter that grade correctly.
Do not guess.
Do not upgrade a grade because you believe a higher grade will improve your chances.
Do not accidentally enter a subject twice while leaving another subject out.
Some universities require candidates to enter O’Level subjects and grades directly into the screening form. The University of Nigeria, Nsukka, for example, instructs candidates to enter verified O’Level subjects and grades carefully during its screening registration.
Before clicking the final submission button, compare every subject and grade with your original result.
8. Uploading the Wrong Document
Another mistake that can affect your Post-UTME application is uploading the wrong document.
Universities may request items such as:
- O’Level results
- JAMB registration details
- Birth certificate or declaration of age
- Passport photograph
- Direct Entry documents
- Payment evidence
- Other supporting documents
The exact requirements vary from one institution to another.
Before uploading a document, check its name, format, size and clarity.
For instance, some university portals specify maximum file sizes or particular image requirements. UNIOSUN’s registration guide, for example, provides specific instructions for passport photograph size and dimensions.
Do not upload a blurry photograph or an unrelated document simply because the portal accepts the file.
9. Uploading a Poor Passport Photograph
Your passport photograph is another detail candidates sometimes overlook.
A photograph that is too dark, blurry, extremely old or unsuitable for identification can create problems, particularly where the university uses the photograph for screening or examination identification.
Use a clear, recent passport photograph that follows the institution’s specifications.
Do not crop a group photograph and assume it will be acceptable.
Do not upload another person’s photograph.
Most importantly, check the university’s official instructions before uploading the image.
10. Paying Through the Wrong Platform
Candidates should be careful when making Post-UTME payments.
Admission periods attract scammers who create fake websites, social media pages and payment instructions.
The safest approach is to start from the university’s official website and follow the admission link provided there.
For example, the University of Lagos directs eligible candidates to its official application portal, while other universities publish their own official application platforms and payment procedures.
Do not send your application fee to an individual’s bank account because someone on social media promised to help you secure admission.
Also, save your payment receipt or transaction reference after making payment.
11. Waiting Until the Last Day to Register
Waiting until the deadline is one of the most avoidable Post-UTME registration mistakes.
Online portals can experience heavy traffic, payment problems, network interruptions or technical difficulties.
If you wait until the final hours, you may not have enough time to resolve a problem.
Universities can also close their portals strictly at the stated deadline. The University of Ibadan, for example, stated for its 2026/2027 screening exercise that there would be no extension of its published registration period.
Register early.
This gives you time to review your application and correct mistakes where corrections are permitted.
12. Failing to Print or Save Your Registration Slip
Completing an online form is not always the final step.
After registration, you may need to print or save your screening slip, examination pass, payment receipt or application confirmation.
These documents may contain your examination date, time, venue, registration number or other important information.
For example, UNILAG instructs successful applicants to print the Post-UTME examination pass, while other institutions provide similar instructions.
Save electronic copies on your phone and, where possible, keep a printed copy.
Do not assume that you will always be able to access the portal later.
13. Failing to Check the Official University Website
One of the biggest admission mistakes is depending entirely on information from friends, WhatsApp groups, Facebook pages or blogs.
Online platforms can be useful for discovering admission news, but the university’s official website should be your final point of verification.
UNILAG has specifically warned prospective candidates to disregard unofficial information and rely on its official communication channels for Post-UTME requirements, registration procedures, deadlines and other admission updates.
Before acting on any admission information, ask:
Where did this information come from?
If it did not come directly from the university or JAMB, verify it before paying money or changing your application.
14. Ignoring Changes Made on JAMB CAPS
Candidates should also pay attention to information that needs to be updated through JAMB.
For example, some institutions make it clear that changes to course or institution must be processed through JAMB rather than simply changing information on the university’s own portal.
The University of Ilorin states that candidates interested in changing courses should make the change on JAMB CAPS, not simply on the university portal.
This is important because the university may reconcile its admission records with JAMB’s records.
If you want to change your course or institution, check the official JAMB procedure and the university’s instructions before taking action.
15. Submitting the Form Without Checking It
This may be the most common mistake of all.
Many candidates rush through the form because they are worried about missing the deadline.
After entering your information, stop and review everything.
Check:
- Your name
- JAMB registration number
- Date of birth
- Phone number
- Email address
- Course
- Institution
- UTME score
- O’Level subjects
- O’Level grades
- Examination numbers
- Passport photograph
- Uploaded documents
- Payment details
Some universities warn that information cannot be changed after final submission. UNIOSUN, for example, states that modification may not be possible after submission and that incorrect information can result in disqualification.
Never treat the final submission button as just another step.
It is the point where your application may become difficult or impossible to change.
What Should You Do If You Make a Post-UTME Registration Mistake?
Do not panic.
First, determine whether the application has already been submitted.
If you have not submitted the form, correct the information immediately.
If you have already submitted it, check whether the university’s portal provides an editing or correction option.
If there is no correction option, contact the university’s official admissions or ICT support channel.
Do not create a second application simply because you made a mistake. JAMB’s FAQ states that candidates should not register more than once and should seek correction rather than obtaining a fresh application document when an error occurs.
Keep your application number, payment receipt and evidence of the error available when contacting the institution.
Most importantly, do not pay an unofficial agent who claims they can secretly change your admission record.
