Two weeks before exams, a thick textbook sits on one side of the table and a folder of past questions sits on the other. Only one of them is getting real attention this week, and choosing wrong wastes days that cannot be gotten back.
Here's the honest past questions vs textbooks comparison, and how to split time between them without guessing.
What Each One Is Actually Good For
Textbooks build understanding. They explain why something works, walk through the logic behind a concept, and connect ideas together in a way that makes the subject actually make sense.
Past questions test performance. They show exactly how a topic gets asked, which angles examiners favour, and how much detail is expected in an answer. A textbook can explain photosynthesis in five pages; a past question shows exactly what WAEC expects written down in an exam-worthy answer.
Neither one replaces the other. The real issue is not choosing between them permanently. It is knowing which one deserves more hours during any specific week before an exam.
When Textbooks Should Get More Time
Early in a term, or when a topic feels genuinely confusing, textbooks deserve the bulk of study time. Jumping straight to past questions on a topic that is not understood yet just leads to memorising answers without grasping why they are correct.
A student struggling to understand chemical bonding needs the textbook's explanation first. Attempting past questions on that topic before understanding the concept usually means guessing between similar-looking options with no real reasoning behind the choice.
Textbooks also matter more for subjects that build on themselves, like Mathematics or Physics. Skipping foundational understanding to jump straight into practice questions creates gaps that show up again later on harder topics building on that same base.
When Past Questions Should Take Over
Once a topic is genuinely understood, and especially once exams are within two to three weeks, past questions should take the majority of study time. This is where marks actually get won or lost.
Examiners repeat patterns more than most students realise. A specific WAEC or JAMB topic often appears in a similar format year after year, sometimes with only the numbers or wording changed. Working through five years of past questions on a topic reveals that pattern clearly, and that pattern is worth more marks than another read-through of the same textbook chapter.
Past questions also expose a gap that textbooks cannot show: the difference between understanding a concept and being able to apply it under real exam pressure, with a clock running and tricky answer options nearby. This guide on studying for multiple-choice exams breaks down exactly how examiners build tricky options, something no textbook will ever explain directly.
A Simple Rule for Splitting Time
A practical split for most subjects: roughly 60% textbook and notes early in a term, flipping to roughly 70% past questions once inside the final month before exams.
This is not a fixed rule for every subject or every student. A subject already well understood from class can shift toward past questions earlier. A subject that still feels shaky deserves more textbook time even close to the exam, since guessing through past questions on an unfamiliar topic wastes time without building real understanding.
Tip: After finishing a topic in the textbook, immediately attempt three to five past questions on that exact topic before moving to the next chapter. This closes the gap between reading and testing early, instead of leaving all practice for the final week.
Using Both Together Instead of Choosing One
The strongest approach does not treat this as either-or. It uses textbooks to build understanding, then immediately tests that understanding with past questions, creating a loop that reinforces both.
Read a topic, close the book, attempt recall from memory, then check with a few past questions on that exact topic. Wrong answers reveal exactly what still needs textbook review, turning the two resources into one connected system instead of two separate piles competing for attention. This pairs naturally with active recall as a study method generally. This comparison of active recall vs rereading explains why testing beats passive review either way.
What to Do With Limited Time Before an Exam
With only a week or two left, and a syllabus not fully covered, past questions become the priority almost automatically. They reveal which topics repeat most often, letting study time concentrate exactly where marks are most likely to come from.
Textbooks in this situation become a reference tool, not a starting point. Look something up only when a past question exposes a gap, rather than reading full chapters from the beginning. For a full day-by-day plan on managing exactly this kind of time crunch, this guide on revising a whole semester's work in one week covers how to prioritise ruthlessly when time is genuinely short.
A Mistake Worth Avoiding
Relying only on past questions without ever building real understanding creates a trap. Memorising answer patterns without grasping the underlying concept works fine until a question gets rephrased slightly, and then the memorised pattern falls apart completely.
Examiners sometimes change past question formats specifically to catch students who memorised answers instead of understanding concepts. Balancing both resources protects against this, rather than gambling everything on one repeating pattern holding steady.
Final Word
The past questions vs textbooks decision is not really about picking a winner. Textbooks build the understanding that makes past questions make sense, and past questions sharpen that understanding into something that survives real exam pressure.
Check the calendar right now. If exams are more than a month away, lean toward textbooks. If they are close, shift hard toward past questions, starting with the topics that appear most often.
