What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to human nutrition. 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 human nutrition, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying bile is an enzyme, or that it digests fat.
- Saying emulsification breaks fat into fatty acids.
- Saying the stomach is alkaline.
- Confusing absorption with digestion, or with assimilation.
- Saying water is absorbed in the small intestine only. Most is, but the large intestine absorbs the rest.
- Saying fibre is digested for energy.
- Listing villi as an adaptation without saying they increase surface area.
Revise it first
