What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to physical quantities and measurement techniques. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on physical quantities and measurement techniques, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Assuming every small division on a scale is worth 1 without counting.
- Using the final reading as a volume instead of the rise in level.
- Timing one oscillation instead of many, or forgetting to divide by the number of oscillations at the end.
- Quoting a mass in newtons or a weight in kilograms.
- Adding perpendicular forces arithmetically instead of using Pythagoras.
- Drawing a correct vector triangle and putting the arrowhead on the resultant the wrong way round.
- Reading a meniscus from above rather than at eye level.
