HOW MARKING WORKS
Where the marks actually go
Biology answers are marked on the specific term and on the link between two ideas. Naming a structure earns one thing; saying what that structure does, and therefore what happens next, earns another. Most lost marks in biology are not wrong facts. They are correct facts that were never joined together, so the causal step the scheme asks for is simply absent.
Handwriting-quality English is not what is being marked. An answer written in short, ungrammatical fragments can score full marks if every required statement is present. But naming the keywords is not enough either. Where the scheme asks you to connect two ideas, listing both without joining them earns nothing for that point. Padding an answer with extra terms in the hope that one of them lands does not work, and can cost you marks a shorter answer would have won.

WHAT YOU GET
Write it as you would in the paper
You practise real O Level biology questions and answer them the way you will on the day. Type them, photograph your handwritten working, or draw straight onto the screen. It comes back marked immediately, point by point. Where you lose a mark you are told exactly what was missing, rather than being shown a model answer and left to spot the difference yourself. If an explanation does not land, you can ask for the same thing again in plain words.
