How O Level students revise, and where the notebook fits

O Level Mathematics is marked on method: a correct answer with no working can lose marks, and a wrong answer with the right method still earns some. Most students revise topic by topic, watching a lesson on one area (similar shapes, simultaneous equations, bearings), then working through topical past paper questions.

Notiq turns that lesson into notes you can actually revise from: the rule, why it works, and each worked example with its steps laid out the way an examiner wants to see them. Formulas are typeset, and every section has a timestamp so you can rewatch only the step you did not follow.

After the notebook, go to past papers. When a question type keeps beating you, find a lesson that covers it, make a notebook, and compare its worked example with your attempt line by line.

Cambridge O Level: frequently asked questions

Does it work for IGCSE Mathematics (0580) too?

Yes. The notebook follows whatever the lesson teaches, and O Level 4024 and IGCSE 0580 share most topics. A lesson made for either works.

Can it handle a past paper walkthrough video?

Yes. On Solver, worked-solution mode turns a video where a teacher solves exam questions into numbered steps per question, with the working and the final answer, which is how method marks are awarded.

What about O Level Physics, Chemistry and Biology?

Paste a lecture from any subject. Science lectures become notebooks with definitions, explanations, equations and examples in the same way; this page focuses on Mathematics because it is the subject most students ask about.

Is it free?

The quiz tool is free to try with no signup. For lecture notebooks, the free plan covers one lecture up to 20 minutes, which fits most single-topic O Level lessons. Paid plans add more and longer lectures.
