TundeTop 10 Mistakes That Make JAMB Candidates Fail UTME
Every year, thousands of candidates lose admission not because they failed JAMB but because of avoidable mistakes.
Many students focus only on reading their textbooks but ignore small errors that can seriously affect their success. Simple mistakes during registration, exam performance, admission processing can cost a candidate an entire academic year.
The Joint Admissions and Matriculation Board (JAMB) is the official body responsible for conducting the UTME in Nigeria, and it operates strictly according to its guidelines. Ignoring these guidelines even slightly can lead to disqualification, low scores, or admission complications.
In this guide, you will discover the most Top 10 Mistakes That Make JAMB Candidates Fail UTME and, more importantly, how to avoid them completely.
Read carefully to avoid costly mistakes in JAMB 2026.
Mistake 1: Choosing the Wrong Subject Combination
One of the biggest mistakes JAMB candidates make is choosing the wrong subject combination during registration.
Many candidates:
- Rely on friends advice
- Follow social media posts
- Ignore the official brochure
Instead of checking the official requirements for their chosen course, they assume any related subjects will work. Unfortunately, this can lead to automatic disqualification, even if the candidate scores very high in the UTME.
For example, selecting the wrong science or social science subject for a professional course can make a candidate ineligible for admission.
Result: Automatic Disqualification
JAMB and universities strictly follow approved subject combinations. If your UTME subjects do not match your course requirements, your admission may be denied regardless of your score.
How to Avoid This Mistake
- Check the official JAMB brochure for your course.
- Confirm the correct subject combination before registration.
- Cross-check with your chosen university’s requirements.
Mistake 2: Registering Late
Another common mistake is waiting until the registration deadline before taking action.
Many candidates delay registration because they assume:
- JAMB will extend the deadline
- There is still “plenty of time”
- Others are also waiting
Problems Caused by Late Registration
- Network congestion
- Long queues at CBT centres
- Limited available exam towns
- Increased stress and rushed decisions
When registration enters the final week, centres become overcrowded, systems slow down, and mistakes become more likely.
How to Avoid This Mistake
- Register as soon as registration opens.
- Avoid waiting until the last week.
- Complete your registration early to secure your preferred exam town.
Mistake 3: Mismatch with NIN Details
A very common and dangerous mistake is having a mismatch between your JAMB details and your NIN (National Identification Number) record.
This usually involves:
- Differences in name spelling
- Wrong date of birth
- Gender mismatch
Since JAMB registration is linked directly to your NIN, any inconsistency can cause serious issues later.
NIN mismatch can lead to:
- Admission processing problems
- CAPS complications
- NYSC mobilization issues
- Certificate data conflicts
Even if you pass JAMB, inconsistent identity records can delay or block admission.
How to Avoid This Mistake
- Verify your NIN details before starting registration.
- Ensure your name and date of birth match exactly.
- If there is an error, correct it at NIMC first before proceeding with JAMB registration.
- Prevention is much easier than correction.
Mistake 4: Ignoring the Official Syllabus
Many candidates prepare for JAMB without using the official syllabus. They read randomly, depend only on class notes, or focus on topics that may not even be examinable.
The Problem
- Studying irrelevant topics
- Missing important high-frequency areas
- Wasting time on non-examinable content
- This leads to poor performance, even for serious students.
How to Avoid This Mistake
- Download the official JAMB syllabus for each subject.
- Study topic-by-topic according to the syllabus.
- Combine syllabus study with past questions.
Mistake 5: Over-Reliance on “Expo” or Runs
Some candidates wait for so-called “expo” or leaked questions instead of preparing properly.
They:
- Trust social media rumours
- Pay scammers promising answers
- Expect last-minute assistance
The Risk
- Losing money to fraudsters
- Exam cancellation
- Disqualification
- Permanent ban from future exams
There is no guaranteed “runs” in JAMB. The exam is computer-based and highly monitored.
How to Avoid This Mistake
- Prepare properly using syllabus and past questions.
- Practice CBT mock tests to improve speed and confidence.
- Trust preparation, not shortcuts.
- Hard work is safer than risk.
Mistake 6: Poor Time Management in CBT
Many candidates enter the exam hall prepared but lose valuable marks because of poor time management.
Common Problems:
- Spending too much time on one difficult question
- Panicking when the timer starts counting down
- Rushing the last section of the exam
Since the UTME is computer-based and strictly timed, mismanaging time can prevent you from answering easy questions you actually know.
How to Avoid This Mistake:
- Practice regularly using timed CBT mock tests.
- Learn to skip difficult questions first and return to them later.
- Answer easier questions quickly to secure guaranteed marks.
Good time control alone can significantly increase your score.
Mistake 7: Choosing the Wrong Course
Another costly mistake is choosing a course without proper research.
Many candidates:
- Follow friends blindly
- Choose popular courses without interest
- Ignore their academic strengths
- Fail to check cut-off marks
This often leads to disappointment when admission lists are released.
How to Avoid This Mistake:
- Research your preferred course thoroughly.
- Check subject combination requirements.
- Review previous cut-off marks.
- Choose a course that matches your strengths and interests.
Smart course selection increases your admission chances.
Mistake 8: Ignoring Post-UTME Requirements
Some candidates believe that once they score high in JAMB, admission is automatic. This is not true.
Many universities conduct:
- Post-UTME screening
- Physical document verification
- Online screening uploads
Missing any of these steps can cost admission.
Common Errors:
- Not checking school announcements
- Missing screening deadlines
- Failing to upload required documents
How to Avoid This Mistake:
- Regularly monitor your chosen schools official portal.
- Keep documents like O’Level results, birth certificate, and JAMB printouts ready.
- Follow instructions carefully.
Admission requires both JAMB performance and proper screening compliance.
Mistake 9: Not Printing Exam Slip Early
Many candidates forget to print their exam slip early enough.
This can result in:
- Not knowing your exact exam date
- Arriving late at the CBT centre
- Confusion about exam town or time
How to Avoid This Mistake:
- Print your exam slip immediately once the portal opens.
- Confirm your exam date and time.
- Visit or confirm your CBT centre location early if possible.
Early preparation prevents last-minute panic.
Mistake 10: Not Practicing Past Questions
One of the biggest reasons candidates score low in JAMB is failure to practice past questions.
Many students read textbooks repeatedly but never test themselves using real exam patterns.
Why This Is a Problem:
- Lack of familiarity with JAMB question style
- Poor understanding of repeated topics
- Slow answering speed during the actual exam
- Difficulty adapting to CBT format
JAMB questions follow a pattern. If you don’t practice, the exam may feel unfamiliar and overwhelming.
How to Avoid This Mistake:
- Solve at least 5–10 years of JAMB past questions.
- Identify frequently repeated topics.
- Practice with CBT simulation apps to improve speed and confidence.
- Time yourself while practicing.
The more you practice, the more confident and faster you become.
Conclusion
Most JAMB failures are not caused by lack of intelligence, they are caused by avoidable mistakes.
Wrong subject combination, late registration, ignoring the syllabus, poor time management, and failure to practice past questions are all preventable errors.
If you:
- Prepare early
- Follow official guidelines
- Use only verified information
- Practice consistently
Your chances of success will increase significantly.
