Knowing content is not enough—biology GCSE questions punish predictable exam technique errors every series.

12 mistakes to fix

1. Treating “explain” like “describe” — explain needs because / mechanism.
2. Ignoring the figure on “using the data” questions — data guide.
3. Missing units on calculations — maths guide.
4. Vague enzymes answers — “denatured” without active site detail.
5. Osmosis without water potential language when the mark scheme expects it.
6. Genetics ratios without showing gametes — inheritance guide.
7. Six-mark lists with no links — extended response guide.
8. Wrong tier or board paper for practice.
9. Not learning required practical methods — practicals guide.
10. Memorising past wording instead of concepts — contexts change.
11. Skipping mark schemes — doing new questions feels productive but teaches little.
12. Revising only favourite topics — Paper 2 genetics/ecology need equal time.
