JAMB Score Converter
Convert your JAMB score to percentage and see how it compares to university cut-offs.
JAMB results come as a single number out of 400, but that number means very little on its own — what matters is how it compares to the cut-off for your course and school. This tool converts your score to a percentage and shows where you stand, so you can decide whether to apply, wait for a change-of-course window, or prepare for a rewrite.

How Is JAMB Score Calculated?
You sit 4 subjects: Use of English (compulsory, 60 questions) and 3 subjects related to your course (40 questions each), for 180 questions total. Each of the 4 subjects is scored out of 100, and the four subject scores are added together — giving a maximum possible score of 400.
Note: JAMB does not give a flat "4 marks per correct answer." Each subject's raw correct-answer count is passed through JAMB's own statistical scoring model (which adjusts for question difficulty) before it's converted to a score out of 100. This is why two candidates with the same number of correct answers in a subject can occasionally end up with slightly different subject scores. There's no publicly documented way to reverse-engineer the exact model, so treat any "X correct answers = Y score" claim you see online as an estimate, not a guarantee.
💡 How to Improve Your Score
Use our free JAMB past questions practice tool. Practicing real questions helps you understand the style, difficulty, and time management.
Some subjects carry more weight in JAMB. Use of English (60 questions), Mathematics/Biology, Chemistry or Physics. Prioritize these.
You have 3 hours for 180 questions = 1 minute per question. Allocate 40 min for Use of English, 50 min each for 3 core subjects.
Don't try to memorize everything. Focus on concepts, formulas, and common question patterns. Every point matters.
Frequently Asked Questions
Out of 400. Each of your 4 subjects (Use of English plus 3 others) is scored out of 100, and the four are added together. Some school portals display an average out of 100 for their own internal ranking — that's a separate figure, not your official JAMB score.
250 and above is generally competitive for most federal universities and courses. 300+ opens up Medicine, Law, and other high-demand courses at top schools. Anything above 200 will usually get you into a state university or a less competitive course, but check the specific cut-off for your course and school before assuming — cut-offs vary every year.
No. JAMB score only gets you past the first screening stage. Most universities also run Post-UTME and combine it with your JAMB score, O'Level results, and catchment area/quota rules to produce a final admission list. A 320 in JAMB doesn't guarantee a spot if your Post-UTME score is weak.
Not for that year's admission cycle — your score is final once released, aside from JAMB's official result-checking/correction window for genuine errors. If your score is too low for your target course, your options are a change of course/institution during the JAMB portal window, or preparing to rewrite the following year.
Score bands and cut-off ranges above are general guides based on recent JAMB admission cycles and may shift each year. Always confirm current cut-offs on your target university's admissions page or the JAMB CAPS portal before making a decision. Last reviewed: October 2026.
