10 Common JAMB Mistakes That Cost Good Students Their First-Choice Course

Every year, students who genuinely knew the material lose their preferred course to avoidable mistakes, not knowledge gaps. Here are the ten that come up most often.

1. Choosing subjects based on what's "easier," not what the course needs

A subject combination that doesn't match your course's actual requirement can quietly disqualify you at the admission stage, no matter how well you scored. Confirm your combination before you register, not after. (See our subject combination guide.)

2. Studying every topic equally

Some topics appear in nearly every year's exam; others rarely show up. Spending identical time on both is a common way to under-prepare for the topics that matter most.

3. Never practicing under time pressure until exam day

Knowing the material and retrieving it in under a minute per question are different skills. Students who only ever study untimed are frequently surprised by how much the clock changes their thinking on exam day.

4. Re-reading instead of self-testing

Re-reading notes feels productive because it's familiar, but it produces a false sense of mastery. Actively answering questions, and getting them wrong in practice where it's cheap, is what actually builds recall.

5. Ignoring wrong answers instead of understanding them

Marking a question wrong and moving on wastes the most useful moment in your entire study session. The "why" behind a wrong answer is usually where the real misconception lives, and it tends to reappear in a different question wrapper if it isn't addressed.

6. Cramming new topics in the final week

The last week has the worst return on new material and the best return on rest, review of already-familiar content, and sleep. Trying to learn a fresh topic three days before the exam is a common source of exam-day panic on unrelated questions too.

7. Underestimating English Language

Because it's compulsory for every course, students sometimes assume it needs less deliberate practice than their "main" subjects. It carries equal weight and deserves equal preparation.

8. Not tracking progress over time

Without a way to see whether a weak topic is actually improving, students often keep doing the same ineffective revision method for weeks. A visible trend, even a simple one, tells you quickly whether to keep going or change approach.

9. Guessing on questions worth revisiting later

Random guessing on a hard question and moving on can mean missing an easier one further down that you'd have had time for. A quick mark-and-return habit protects your overall score far better than fighting one question to the end.

10. Registering details incorrectly

Small errors in registration details (names not matching ID documents, wrong exam centre choice, mismatched subject combination) create administrative problems that have nothing to do with academic readiness but can still derail admission. This step deserves the same care as studying.

Most of these come down to one thing: not being able to see your own patterns clearly. Kreench's adaptive practice surfaces your weak topics automatically instead of leaving you to guess, and the AI tutor explains why an answer is wrong the moment you get it wrong, not three weeks later when you've forgotten the question. On Silver and above, topic-priority tracking shows exactly which topics are still dragging your accuracy down, ranked, so you're never spending equal time on things that don't need it equally.
