Overview
Physics & Maths Tutor (PMT) is an incredibly popular and useful free resource, especially for its vast library of past papers and revision notes for STEM subjects. However, a complete revision strategy requires more than just access to questions and solutions; it requires a way to accurately gauge your own performance. This is where MarkScheme provides a powerful, free alternative by focusing on the crucial step of marking your own work against the official Cambridge criteria.
What is Physics & Maths Tutor and What Is It Best For?
Physics & Maths Tutor has earned its reputation as a go-to site for millions of students, and for good reason. It offers a massive, well-organised collection of past papers, detailed revision notes, flashcards, and mind maps, with a strong focus on GCSE and A-Level sciences and mathematics. One of its most valued features is its compilation of questions by topic, allowing you to drill down on specific areas of the syllabus where you feel less confident. As a free repository of practice materials and content summaries, it serves as an excellent first stop for gathering resources and reinforcing your subject knowledge.
Always Start with the Source: Official Cambridge Materials
Before you dive into any third-party website, your revision must be anchored by the official materials provided for free by Cambridge International itself. These are the past papers, the mark schemes, and the examiner reports. While past papers and mark schemes give you the questions and the correct answers, the examiner reports are a goldmine of information, explaining where students commonly went wrong, what excellent answers looked like, and how examiners interpreted the questions. These documents are the ultimate source of truth, as they are created by the same people who will be marking your final exam.
The Missing Link: From Looking at Solutions to Earning Marks
There is a significant difference between passively reading a model answer and actively marking your own attempt. A worked solution, like those found on PMT, shows you one way to get to the correct answer, which is helpful for understanding the method. However, it doesn't teach you how to think like an examiner or how to structure your own, unique answer to meet the specific demands of the mark scheme. Without practising the skill of applying a mark scheme to your own work, you risk misunderstanding where marks are actually awarded and repeating the same mistakes.
How MarkScheme Provides a True Alternative
MarkScheme was built to solve this exact problem. It's not just another library of papers; it's a purpose-built tool that transforms the difficult task of self-assessment into a simple, effective process. After completing a past paper, you upload a photo of your handwritten script. MarkScheme then presents your answer side-by-side with the relevant lines from the official mark scheme, allowing you to award marks, add comments, and see exactly how your performance stacks up. This process of [free marking](/mark) makes you an active participant in your revision, builds exam technique, and covers a wide range of subjects, including many humanities that are less of a focus for PMT.
Comparing Your Free Cambridge Revision Options
For Cambridge free Cambridge revision resources, to build the best revision plan, it's helpful to understand what each resource is designed to do. While all are free, they serve different functions within your study schedule. Using them in combination gives you a significant advantage.
| Resource | Best for | Cost |
|---|---|---|
| Official Cambridge Resources | Authoritative past papers, mark schemes, and examiner reports. | Free |
| Physics & Maths Tutor | STEM notes, worked solutions, and question banks by topic. | Free |
| MarkScheme | Accurately self-marking handwritten work against official schemes. | Free |
Building an Effective Revision Workflow
For the most effective preparation, you should integrate these resources into a structured cycle. Start by downloading an official past paper and its associated files from the Cambridge support hub. Attempt the paper under timed, exam-like conditions to simulate the real experience. Once finished, use the MarkScheme tool to conduct a rigorous, line-by-line marking of your script. This will highlight your strengths and weaknesses with pinpoint accuracy. For any content gaps revealed during marking, you can then turn to PMT's notes or our own [free courses](/courses) to review the material. Finally, read the official Examiner Report for that paper to understand the common pitfalls and what examiners were looking for, a step that ties everything together. This methodical approach is one of the pillars of our guide to the [best free Cambridge revision resources](/blog/best-free-cambridge-revision-resources-2026).
Frequently asked questions
This section covers Frequently asked questions — ranked by what Cambridge examiners return to most often in past papers.
Is Physics & Maths Tutor accurate for Cambridge exams?
PMT is an excellent resource for practice questions and revision notes compiled from various exam boards. While generally reliable, the notes are an interpretation of the syllabus, not the official text. For 100% accuracy on marking criteria and exam expectations, you must always prioritise the official Cambridge mark schemes and examiner reports.
Why can't I just read the mark scheme PDF?
You can, but it's inefficient. Juggling your handwritten script, the question paper, and a separate mark scheme PDF is cumbersome and makes it easy to be overly generous with your marking. MarkScheme's interface puts your answer directly next to the marking criteria, forcing an honest, focused assessment that builds real exam skill.
Does MarkScheme cover subjects other than Physics and Maths?
Yes, absolutely. While our name reflects our origins, MarkScheme is designed for all Cambridge International subjects, from Biology and Chemistry to History, English, and Economics. Our goal is to provide a universal tool for accurate self-marking across the humanities, sciences, and everything in between, complementing the STEM focus of other platforms.
