Mark scheme questions
Where can I find IGCSE mark schemes?

How do I read a Cambridge mark scheme?
Start with the generic marking principles at the front, which apply to every question. Then each answer's points: M marks are for method, A marks for an accurate answer that usually depends on the method mark, B marks stand on their own, and 'ecf' or 'ft' lets a wrong earlier answer still earn later marks.
Can AI mark my paper with the mark scheme?
Yes. Upload a past paper you've done and CIE Buddy marks it question by question against that paper's own mark scheme, following Cambridge's marking rules, and explains every mark you lost. It's a close guide, not an official Cambridge grade.
