Crack AQA Combined Science GCSE — all three sciences, one clear path

If you're reading this, there's a good chance you — or someone you love — is staring at a Combined Science revision guide that's 400 pages thick, wondering where on earth to start. Maybe mocks are coming up fast. Maybe certain topics (looking at you, moles and hormonal coordination) feel completely impenetrable. Maybe you've been doing past papers and the mark schemes might as well be written in a foreign language. I get it. That gap between "I kind of understand this" and "I can actually answer the exam question" is exactly where students lose marks — and it's exactly what this school is built to close.

I created AQA Science Decoded because I kept seeing the same thing: students who genuinely knew their science but didn't know how to communicate it in the way AQA rewards. They'd write a perfectly reasonable answer and pick up one mark out of four, because they didn't spot that the command word was "evaluate," not "describe." Or they'd freeze on a six-mark calculation because no one had shown them how to set out their working in a mark-winning way. This school is my answer to that problem — a structured, specification-locked route through all three sciences that teaches the content and the exam craft at the same time.

Here's what you'll find inside. Biology starts with cells and organisation, builds through genetics, homeostasis, and hormonal systems, and finishes with evolution and ecosystems — all the terminology you need, all the diagrams decoded. Chemistry takes you from atomic structure and bonding through to organic chemistry, rates of reaction, equilibrium, and Earth's atmosphere, with every calculation type broken down into clear, repeatable steps. Physics covers forces, electricity, and waves before moving into magnetism, radioactivity, and space — with a strong focus on the multi-step equation questions that separate the good grades from the great ones. And right at the end, the Exam Skills section brings it all together: command word mastery, a revision strategy built on spaced practice, and a past-paper triage system to make sure you're spending your final revision hours in exactly the right places.

I know that some of you are parents who haven't opened a science textbook since you were a teenager — welcome, this is for you too. The lessons are written to be genuinely clear, not dumbed down, and many parents use this school to stay involved in their child's revision in a really practical way. And if you're a tutor looking for structured, specification-accurate content to anchor your sessions, you'll find the topic-by-topic layout makes it easy to slot into the work you're already doing.

The exams are very learnable. The specification is finite. The mark schemes follow patterns. Come and let me show you exactly what those patterns are — and how to hit them every time.
