About Diagnostic Questions

On Diagnostic Questions we have over 10,000 top-quality, free mathematics questions designed to help you and your students identify, understand and resolve key misconceptions.

These are not your traditional multiple choice questions.

Each time your students answer, they are prompted to give an explanation for their choice. It is this explanation, combined with our unique data engine, that enables you as a teacher to pin-point the specific nature of their misconception.

Moreover, students with misconceptions can benefit from reading 1000s of top quality correct explanations, written by students from all over the world until they find the magic one that makes sense to them.
