The way most candidates do it
Open the book, work through a set, check the answers at the back, note the score, feel briefly good or bad, move to the next set. Nothing about that process makes the next attempt better. The questions you got right taught you nothing new, and the ones you got wrong were corrected and immediately forgotten.
That is also the trap with past questions shared in JAMB Telegram groups: collecting them feels like progress. If you are choosing a tool to practise with, here is what to look for.
Time everything, from the start
An untimed question is a different skill from a timed one. Set a clock for every set, even a short one. You are training the thing the exam measures: accuracy at a required pace. Working comfortably and slowly builds a false picture that the exam then corrects, expensively.
Keep an error log, and make it useful
For every wrong answer, record three things: the topic, the correct answer, and why you missed it. That last one matters most, and there are only a few honest options:
- I never learned this. A gap — schedule the topic.
- I knew it and slipped. Carelessness — a pacing or attention problem, not a knowledge one.
- I misread the question. A reading problem, fixed by underlining what is actually being asked.
- I guessed and got lucky, or guessed and did not. Mark the lucky ones too. A correct guess is an unlearned topic wearing a disguise.
After two weeks, the log tells you what to revise far better than any syllabus can, because it is about you specifically.
Repeat the ones you got wrong. On purpose. Later.
This is the step almost everyone skips. Redo your wrong questions after a few days, then again after a couple of weeks. The delay is the point: retrieving something you have partly forgotten is what moves it into durable memory. Redoing it immediately, while the answer is still fresh, mostly proves you can remember what you read a minute ago.
Do not memorise answers
Candidates who drill the same booklet repeatedly start recognising questions by shape and recalling that the answer was C. That is not knowledge, and the exam will reword the item just enough to break it. Rotate sources, and when you review, make yourself explain why the answer is right — if you cannot, you have memorised a letter.
Mix subjects and topics once you are past coverage
Practising twenty questions from one topic in a row is easier than it should be, because you already know what kind of question is coming. The real paper interleaves. Once you have covered a topic, practise it mixed in with others, which is harder, feels worse, and works better.
Questions people ask
What is the wrong way to use JAMB past questions?
Working through a set, checking the answers at the back, noting the score and moving on. The questions you got right taught you nothing new, and the ones you got wrong were corrected and immediately forgotten.
What should an error log record?
Three things for every wrong answer: the topic, the correct answer, and why you missed it. The honest options are that you never learned it, you knew it and slipped, you misread the question, or you guessed. Mark the lucky guesses too, because a correct guess is an unlearned topic wearing a disguise.
When should I redo the questions I got wrong?
After a few days, then again after a couple of weeks. The delay is the point. Retrieving something you have partly forgotten is what moves it into durable memory, while redoing it immediately mostly proves you can remember what you read a minute ago.
Why should I not drill the same booklet over and over?
You start recognising questions by shape and recalling that the answer was C. That is not knowledge, and the exam will reword the item just enough to break it. Rotate sources, and make yourself explain why the answer is right.
