How to study a subject you don't understand
Almost everyone has a subject that "doesn't enter". Usually the problem isn't you — it's a missing foundation, or an explanation that didn't suit you. Both can be fixed.
1. Find exactly where you get lost
"I don't understand Physics" is too big to fix. Go through a topic slowly and stop at the first line you can't follow. That line is your real problem. Often it's something from an earlier class.
2. Go back to the basics
Many topics build on earlier ones. If you can't do quadratic equations, the problem may be algebra from JSS. Go back to that earlier topic, learn it properly, then return. It feels slow, but it's the fastest way forward.
3. Try a different explanation
If one textbook confuses you, try another, or a good video lesson on the same topic. Sometimes a different example or diagram makes everything click.
4. Learn from worked examples first
For calculations, study a fully solved example line by line. Cover the solution and try to rewrite it yourself. Then try a similar question alone. Only then move on to new questions.
5. Ask good questions
When you ask a teacher, classmate or tutor, show them the exact step where you are stuck. "I don't understand why this becomes x² here" gets you a far better answer than "I don't understand this topic".
6. Practise in small steps
Start with easy questions on one topic until you get them right, then slightly harder ones. Getting questions right builds confidence, and confidence makes the next topic easier.
7. Give it your best hours
Study your hardest subject when you're most alert, and give it more time in your timetable (tick "Hard for me").
8. Don't give up on it
Every JAMB subject counts. Moving a weak subject from 30 to 55 can raise your total more than pushing a strong one from 70 to 75.
