What this library covers

192 original maths and physics practice questions across 16 selected topic collections, with notes, hints and worked examples. These teach concepts shared across IGCSE courses. They are not complete Cambridge or Edexcel syllabus coverage, official exam papers, endorsed resources or predicted exam grades. Advanced topics and practical skills remain incomplete.

How the material was made

The new questions, notes and lab guides were drafted using GPT-6 Luna with high reasoning, at the owner's request. Automated structural checks and numerical spot checks support the release. Independent teacher review is pending. Report mistakes to support@preptula.com, including the question ID or page address. This is free concept practice while review continues.

Practice points and diagnostic results

Automatic checking assesses the final numerical answer or selected option. Practice points are awarded only for a correct final answer, not for written working. The diagnostic samples two questions per topic and recommends revision starting points; it is not a reliable measure of mastery or an exam grade. Hints and full worked reasoning support learning after each attempt.

Your progress and privacy

Practice attempts and the latest diagnostic summary are saved only in local storage on this browser. They do not sync across devices. Use “Clear practice progress” in the footer to delete this practice data; the existing study desk has separate controls for its older lessons and choices. If browser storage is disabled, practice still works for the current visit.

Shared tutor sets

Creating a practice link sends only a subject and a list of question IDs to our Cloudflare Worker. Sets are stored in a separate PrepTula PostgreSQL database on our VPS for up to 180 days, then deleted by a daily cleanup. Links are accessible to anyone who has them. No student names, emails, answers or scores are stored with a set. The VPS hosts other services in separate databases; this feature uses only PrepTula's database. Cloudflare and our server provider process technical request information to deliver and protect the service. We do not use advertising trackers.

Open-source tools

Maths graph labs use JSXGraph, self-hosted under its MIT licence. Physics labs use original Canvas code and simplified equations; each lab states its assumptions. Competitor sites informed navigation research; their question text, diagrams and solutions were not copied.
