How to Avoid Common JAMB Registration Mistakes (Main Guide)

Below is a complete and simple guide to help you avoid the common problems that affect many students during JAMB registration. Follow each step carefully, and you will save yourself from stress later.
1. Use the Correct and Active Phone Number
One of the biggest JAMB registration mistakes is using the wrong phone number or a number that is not active. Your phone number is very important because:
-
Your JAMB Profile Code will come through SMS.
-
All updates from JAMB will come to that number.
-
You will need the number for future login and confirmation.
What to do:
Use a phone number that belongs to you and will remain active until admission is completed. Do not use your friend’s number or a random number you may forget.
2. Use a Reliable and Accessible Email Address
Another common mistake is using an email address that you do not have access to. Some students even forget the password to their email.
Your JAMB login details and your admission updates will come through your email, so it must be correct.
What to do:
-
Create a simple Gmail account.
-
Use a password you will never forget.
-
Write down the email and password in a safe place.
3. Make Sure Your Names Match Your NIN Records
JAMB now works with NIN, and this means your names on JAMB must match your NIN exactly. If your names do not match, your registration may be rejected.
What to do:
-
Check your NIN slip before registration.
-
If your name is wrong on NIN, go to NIMC office and correct it.
-
Make sure your surname, first name, and middle name are in the right order.
This will help you avoid problems later when printing your admission letter.
4. Choose the Right Subjects for Your Course
Wrong subject combination is one mistake that can destroy your admission dream, even if you score high in JAMB.
What to do:
-
Check the official JAMB Brochure.
-
Confirm the correct subjects for your course.
-
Ask your school counselor or a trusted teacher if you are confused.
Do not guess your subject combination. A small mistake here can stop you from getting admission.
5. Select the Right Course and Institution
Some students choose courses they do not like or schools they cannot meet the cutoff mark for. Others choose courses without understanding what the course requires.
What to do:
-
Choose a course that matches your interest.
-
Check the cutoff marks for the school you want.
-
Have at least 3 options: First choice, second choice, and backup.
A smart choice now will save you trouble later.
6. Make Sure You Understand Your O’Level Requirements
Your WAEC, NECO, or NABTEB results must match the course you are choosing. Some students choose courses that require certain subjects, but their O’Level result does not have those subjects.
What to do:
-
Check the needed subjects for your course.
-
Make sure you have credit passes in required subjects.
-
If you are using awaiting result, be sure you can meet the requirements.
7. Register Only at an Approved JAMB CBT Center
Many students go to cyber cafés that are not approved by JAMB. This can lead to:
-
Wrong data entry
-
Fake registration
-
Missing details
-
Wrong subject choices
What to do:
Always register only at an approved JAMB CBT center. This will protect you from errors and fraud.
8. Avoid Rushing Through Your Registration
Most mistakes happen when you rush. Students who want to register fast end up choosing wrong subjects, wrong schools, or wrong details.
What to do:
-
Take your time.
-
Read everything carefully.
-
Ask questions if you are unsure.
Do not allow pressure from friends to push you into making mistakes.
9. Review All Details Before Final Submission
At the CBT center, the system will show your information before final submission. Many students do not check carefully.
Make sure you check the following:
-
Your name
-
Your date of birth
-
Your email
-
Your phone number
-
Your subject combination
-
Your course
-
Your school choices
Once you click submit and it is uploaded, it cannot be changed easily.
10. Keep All Your Receipts and Printouts Safe
After registration, JAMB will give you:
-
Registration slip
-
Payment receipt
-
Subject list
-
Personal details
These documents are very important during exam day and admission period.
What to do:
-
Make photocopies
-
Save a soft copy on your phone
-
Keep the original in a safe place
11. Follow JAMB Instructions Strictly
Every year, JAMB releases instructions about registration, exams, corrections, and requirements. If you follow wrong information from social media, you may make mistakes.
What to do:
-
Check JAMB’s official website
-
Follow approved CBT centers
-
Ask trusted teachers
Do not depend on rumors online.
12. Avoid Fake Agents and Fraudsters
Many students lose money because they follow fake agents who promise special help or shortcuts.
There is no shortcut in JAMB.
What to do:
-
Avoid people who say they can change your score
-
Avoid those who say they can secure admission for money
-
Only work with approved CBT centers
13. Do Not Wait Until the Closing Date
Many mistakes happen when you register late because the crowd becomes too much.
What to do:
Register early.
This gives you time to correct any issue before the deadline.
14. Make Sure Your Passport Photo Is Clear
Your passport will appear on your JAMB slip and exam documents. A wrong or unclear passport can cause confusion.
What to do:
-
Use a clear and recent passport
-
Do not use filtered photos
-
Make sure your face is visible
15. Understand the JAMB Correction of Data Process
If you make a mistake, JAMB allows correction, but not all mistakes can be corrected easily.
You can correct:
-
Names
-
Gender
-
State
-
Local government
-
Course
-
Institution
What to do:
-
Visit a CBT center
-
Pay for correction of data
-
Follow the official steps
But the best thing is to avoid mistakes from the beginning.
