How Many Practice Questions Should You Do a Day?
Abdulrahman YunisAI Engineer
Twenty to forty reviewed properly, not a hundred rushed. The number that matters is how many you understand afterwards, not how many you answered.
Twenty to forty a day for most courses, reviewed properly afterwards. For a high volume professional exam in a dedicated study period, seventy five to a hundred and twenty five, but only if you are reading every explanation.
The number people quote is almost always the wrong number, because they are counting questions answered rather than questions understood.
The ratio that actually sets your limit
A practice question has two parts: answering it, and finding out why the answer was what it was. The second part is where the learning happens and it takes two to three times as long as the first.
So the real constraint is not how fast you can answer. It is how many explanations you have the attention to read carefully. Forty questions with forty explanations read properly takes about ninety minutes. A hundred questions with explanations skimmed takes the same ninety minutes and teaches you a fraction as much.
If you are finishing a hundred questions in an hour, you are not doing practice questions. You are taking a test you will learn nothing from.
Setting your number
Work backwards from time, the same way you would with flashcards.
Decide the session length first. Allow roughly two minutes per question for answering and reviewing combined on standard material, more for clinical vignettes or multi step problems. Then set the cap below what the time allows and stop when the time runs out rather than when the queue empties.
| Situation | Questions per day | Notes |
|---|---|---|
| Normal term, alongside lectures | 20 to 40 | Mixed across topics, not just this week’s |
| Final month before a university exam | 40 to 60 | Add a weekly timed full length set |
| Dedicated professional exam period | 75 to 125 | Only sustainable if it is your main daily activity |
| The last week before any exam | Reduce by half | Review your error log instead of adding volume |
That last row surprises people. Volume in the final week produces fatigue and very little new learning, and the error log you have been keeping is worth more than another fifty questions.
Why questions beat reading
This is not a preference. Answering under uncertainty and then being corrected produces a much stronger memory than reading the same content, and the effect is one of the better established findings in the field.
Practice testing and distributed practice were the two highest utility strategies in Dunlosky and colleagues’ 2013 review of ten study techniques, with rereading and highlighting near the bottom. Most people invert this in practice: weeks of reading, then questions at the end as a check. Doing questions first, badly, and letting them direct your reading is the more efficient order even though it feels wrong.
The error log
One line per missed question. What was asked, why you chose what you chose, what the actual reasoning was. Not the correct answer, the reasoning.
After two or three weeks, patterns appear that no amount of self reflection would have produced. Most people find their errors are not spread evenly across content, they cluster into two or three process mistakes. Missing the word “first” or “most likely”. Picking the most thorough option rather than the most urgent. Rushing the last ten items.
Those are fixable in a way that content gaps are not, and they cost more marks across a full paper than any single topic does.
Mixed sets, not topic sets
Doing forty questions from the chapter you just read is a much easier task than the exam, because you already know which method applies. Pull questions from across topics so that identifying what the question is about is part of the work.
Your accuracy will drop. That is the point, and it is a better simulation of the real thing.
Getting it right when you got it right
Read the explanation even for correct answers. Guessing correctly, or picking the right option for a wrong reason, is extremely common and completely invisible if you only review your mistakes.
A useful habit: before you look at the explanation, say in one sentence why your answer is right and why one other option is wrong. If you cannot do both, treat it as a miss regardless of what the score says.
When you fall behind
You will, usually the week something else goes wrong.
Do not clear the backlog in one sitting. A two hundred question catch up session produces almost no retrieval and a strong desire never to open the bank again. Cap the session as normal and prioritise within the backlog: previously missed questions first, untouched ones last.
If the backlog keeps growing, your daily target was set above your actual capacity. Lower it. A sustainable thirty a day beats an aspirational eighty you hit twice a week.
Where a tool fits
Commercial question banks cover the standard syllabus. What they do not cover is what your specific course emphasised, and that is usually where your exam differs from the generic version.
That is what StudyLabAI’s exam practice generator is for. Upload your notes, slides or course files and get timed practice with scoring from that specific material, to run alongside whatever bank you are using. It handles producing the questions. Reading every explanation and keeping the error log is the part that does the work.
Common questions
Is it better to do questions timed or untimed?
Untimed while you are learning a topic, timed once you know it. Timing trains pacing, which is a real constraint, but adding time pressure to material you do not know yet just produces guessing.
Should I do questions before I have covered the material?
Yes, earlier than feels comfortable. You will get most of them wrong and that is informative. Questions direct your reading far more efficiently than a syllabus does.
How many questions in total before an exam?
Total count matters much less than review quality. A thousand questions reviewed properly beats three thousand rushed, and the people who quote enormous totals usually did the second thing.
What percentage should I be scoring?
On mixed sets of material you are still learning, anywhere from forty to seventy percent is normal. A consistently high score usually means your sets are too narrow.
Do I need to redo questions I got wrong?
Yes, after a gap of a few days rather than immediately. Immediately afterwards you are recalling the explanation, not the reasoning.
