JAMB / UTME
JAMB Aggregate Score Calculator
Every Nigerian university uses an admission aggregate, not your raw JAMB score, to decide whether you get a course. The aggregate combines your JAMB (UTME) result, the university's own post-UTME, and your O'Level grades into a single number out of 100. Different schools weight the three components differently, but the standard 50/30/20 split (half UTME, thirty post-UTME, twenty O'Level) is what most federal and state universities publish in their brochures.
This calculator turns those three inputs into an honest aggregate in seconds, so you can see whether your score is competitive for medicine, law, engineering, or any other high-demand course before JAMB releases admission lists. Enter your JAMB score, your post-UTME if you've sat for one, and your five best O'Level credits. We'll show every contribution separately and flag where your total sits against the bands Nigerian universities actually use. Nothing is sent to a server; calculations happen in your browser.
Enter your scores
Default weighting is 50 / 30 / 20 (UTME / Post-UTME / O'Level). Leave post-UTME blank if your school doesn't run one.
Your 5 best O'Level credits
Pick the grade from your WAEC, NECO, or NABTEB result. Only credits (A1–C6) count.
How the JAMB aggregate is calculated
The standard formula used by most Nigerian universities is 50 / 30 / 20:
- UTME contribution (50%): your JAMB score out of 400, divided by 8. A 320 in JAMB becomes 40 out of a possible 50.
- Post-UTME contribution (30%): your post-UTME score out of 100, multiplied by 0.3. An 80 becomes 24 out of a possible 30.
- O'Level contribution (20%): graded points for your five best subjects: A1 counts as 10, B2 as 9, B3 as 8, C4 as 7, C5 as 6, C6 as 5. The total is capped at 20.
Add the three contributions for an aggregate out of 100. Some private and state universities (Babcock, Covenant, LASU) use slightly different weights, and a handful of universities skip post-UTME entirely and use 60/40 (UTME / O'Level). Always check the current admission brochure for the school you're applying to. This tool defaults to the formula most schools publish.
Reading your aggregate
The four bands the calculator shows you reflect what Nigerian universities actually offer course-by-course, not just the JAMB minimum cut-off:
- Below 50: likely insufficient for most degree programmes. Consider a polytechnic, college of education, or a re-sit of JAMB with stronger O'Level credits.
- 50 to 65: competitive for private universities and many state universities. Less competitive for federal universities outside the high-demand courses.
- 65 to 80: strong for federal universities in most courses, with realistic admission for engineering, computer science, and accounting at second-choice federal schools.
- 80 and above: very strong. This is the range needed for the most competitive programmes (medicine and surgery, law, pharmacy, dentistry) at first-choice federal universities like UI, UNILAG, OAU, ABU, and UNN.
Common pitfalls
Three mistakes we see candidates make every year:
- Counting more than 5 O'Level subjects. Only your five best credits count. A sixth credit doesn't lift the aggregate; it can only fill in for a missing required subject.
- Forgetting subject combinations. Your aggregate is only relevant if your JAMB and O'Level subjects match the course. For medicine you must have credits in English, Maths, Biology, Chemistry, and Physics. For engineering you need Physics and Chemistry alongside Maths.
- Assuming the same formula everywhere. Always check the brochure for the specific school you're applying to. Some private universities replace post-UTME with an interview, and a few federal universities weight UTME at 60 instead of 50.
What to do with the result
If you are still preparing for JAMB or post-UTME, our JAMB UTME 2026 guide walks through the CBT mechanics, the subject combinations for every course, and the study moves that take a 220 candidate to 300+. If your O'Level credits are the weak link, the how-to-pass-WAEC guide covers a 90-day plan per subject. If you're a school running JAMB prep for SS3 students, LearnStack's exam-mode runs unlimited mocks against past papers and tracks class-wide weaknesses.
