The Joint Admissions and Matriculation Board (JAMB) registration is the gateway to securing admission into Nigerian tertiary institutions. However, even minor mistakes during registration can lead to disqualification or delays. Based on JAMB’s latest guidelines and lessons from past candidates, here are the top 10 mistakes to avoid for a seamless JAMB 2025 registration.  

1. Choosing the Wrong Subject Combination
Why It’s a Problem: Your subject combination directly affects your eligibility for your chosen course. For example, Medicine requires English, Biology, Chemistry, and Physics. Selecting the wrong subjects can disqualify you during admission screening.  
How to Avoid It:  
- Check the JAMB brochure: Verify the correct subjects for your course.  
- Consult teachers/counselors: Confirm the right combinations, especially for competitive programs.  
- Double-check before submission: Ensure your choices align with university requirements.  

2. Entering Incorrect Personal Information 
Why It’s a Problem: Errors in names, birthdates, or states of origin can invalidate your application. If your name on JAMB doesn’t match your NIN record, you may face delays.  
How to Avoid It:  
- Cross-check with official documents: Use the exact details from your birth certificate and NIN.  
- Review twice before submitting: Check spellings, dates, and state/LGA details carefully.  

3. Registering at Unauthorized Center  
Why It’s a Problem: Fraudulent centers may overcharge, enter incorrect details, or use outdated software, putting your registration at risk.  
How to Avoid It: 
- Use JAMB-accredited CBT centers: Verify accreditation on JAMB’s official portal.  
- Report suspicious centers: Contact JAMB at support@jamb.gov.ng.  

4. Procrastinating Until the Last Minute  
Why It’s a Problem: Late registrations lead to overcrowded centers, technical issues, and rushed errors. The 2025 registration closes on March 8, 2025—don’t wait!  
How to Avoid It:  
- Mark key dates: Registration starts on **January 31, 2025**.  
- Start early: Complete your profile and payment within the first two weeks.  

5. Using an Invalid Email or Phone Number 
Why It’s a Problem: JAMB sends critical updates (exam slips, results) via email and SMS. If your contact details are incorrect, you may miss important information.  
How to Avoid It:  
- Create a dedicated email: Use Gmail or Yahoo for reliability.  
- Test your phone number: Send a trial SMS to confirm connectivity.  

6. Skipping Biometric Verification  
Why It’s a Problem: Biometric data (fingerprints, photos) is mandatory. If you fail to verify, your registration will be invalid.  
How to Avoid It: 
- Keep your fingers clean: Remove dirt or henna before scanning.  
- Visit accredited centers: Ensure they use JAMB-approved biometric devices.  

7. Uploading Blurred or Incorrect Documents  
Why It’s a Problem: Unclear O’Level results or passport photos can lead to rejection. WAEC/NECO results must be scanned at 300 DPI for clarity.  
How to Avoid It:  
- Follow JAMB’s guidelines: 
  - Passport photo: White background, taken within the last three months.  
  - Documents: Save as PDF (≤2MB).  
- Preview uploads: Ensure clarity before submission.  

8. Creating Multiple JAMB Profiles  
Why It’s a Problem: Multiple registrations are flagged as malpractice. If you forget your login details, retrieve them instead of creating a new profile.  
How to Avoid It:  
- Save your profile code: Write it down or store it on your phone.  
- Use one email/phone number: Avoid mixing contact details.  

9. Ignoring the Mock Exam  
Why It’s a Problem: The mock exam (₦3,500 fee) familiarizes candidates with the CBT format. Skipping it may increase anxiety on the actual exam day.  
How to Avoid It:  
- Opt-in during registration: Select the mock exam option.  
- Practice online: Use apps like EduPadi’s CBT simulator.  

10. Payment Errors and Fraud  
Why It’s a Problem: Unapproved agents may scam you, and failed transactions can delay registration.  
How to Avoid It:  
- Use official payment channels: Purchase e-PINs via JAMB’s portal or accredited banks.  
- Keep payment receipts: Save transaction IDs for reference.
