The curriculum
What's inside your school
6 modules · 20 lessons
Biology: Life, Cells & Systems
Covers every core Biology topic on the GCSE Combined Science specification — from cell biology and genetics to ecosystems and disease — with clear explanations, required practical walkthroughs, and exam-focused application at every step.
- 1.1Cells, Transport & MicroscopyIncluded
- 1.2Genetics, Inheritance & EvolutionIncluded
- 1.3Body Systems, Disease & HealthIncluded
- 1.4Ecology, Ecosystems & BiodiversityIncluded
Chemistry: Atoms, Reactions & the Material World
Walks students through every core Chemistry topic — atomic structure, bonding, quantitative chemistry, reactions, and the Earth's atmosphere — building the conceptual understanding and calculation confidence needed across all Chemistry exam papers.
- 2.1Atomic Structure, the Periodic Table & BondingIncluded
- 2.2Quantitative Chemistry & Chemical CalculationsIncluded
- 2.3Chemical Changes, Energy & Rates of ReactionIncluded
- 2.4Organic Chemistry, Polymers & the AtmosphereIncluded
Physics: Forces, Energy & Waves
Covers the core Physics topics of forces, motion, energy stores and transfers, and waves — building both conceptual understanding and the equation-handling confidence students need to score on every calculation and application question.
- 3.1Energy Stores, Transfers & EfficiencyIncluded
- 3.2Forces, Motion & Newton's LawsIncluded
- 3.3Waves, Electromagnetic Spectrum & SoundIncluded
Physics: Electricity, Magnetism & Space
Completes the Physics specification with electricity, circuits, magnetism, and space physics — ensuring students can handle circuit calculations, explain electromagnetic effects, and approach the less familiar space topic with structured confidence.
- 4.1Electricity & CircuitsIncluded
- 4.2Magnetism, Electromagnetism & Induced EMFIncluded
- 4.3Space Physics & the UniverseIncluded
Exam Maths, Required Practicals & Scientific Skills
Directly addresses the maths and practical skills that cut across all three sciences — rearranging equations, graph work, unit conversions, significant figures, and required practical questions — building the cross-science toolkit students need to stop losing easy marks.
- 5.1Rearranging Equations & Tackling Science MathsIncluded
- 5.2Graphs, Units, Significant Figures & Data InterpretationIncluded
- 5.3Required Practicals MasterclassIncluded
Exam Technique, Revision Strategy & Confidence
Brings everything together by teaching students how to decode any exam question, write mark-scheme-aligned answers, build a personalised revision plan, and manage exam-day performance — so they walk into all six papers with strategy, not panic.
- 6.1Decoding Command Words & Structuring Exam AnswersIncluded
- 6.2Memory Techniques & Spaced Retrieval PracticeIncluded
- 6.3Building Your Revision Plan & Exam-Day StrategyIncluded
Who it's for
Is this you?
The Year 11 Rusher
Exams are months away and the specification still feels enormous — needs a focused, fast-track plan right now.
The Year 9 Starter
Just beginning the GCSE course and wants to build strong foundations from day one rather than cram later.
The Anxious Parent
Wants to support their child's revision at home but isn't confident enough in the science content to help directly.
The Grade Boundary Climber
Sitting just below a target grade and looking for the specific clarity and exam technique to push over the line.
The Self-Taught Learner
Home-educated or studying independently and needs a structured, complete course without relying on a classroom.
The Concept Struggler
Finds science confusing because it was never properly explained — needs clear, jargon-free lessons that rebuild understanding from scratch.

Geoffrey Mitchell
I know exactly what it feels like to stare at a GCSE Science specification and wonder where on earth to begin.
Three subjects. Six exams. Hundreds of topics, equations, and required practicals — and somehow you're expected to hold all of it in your head at once. If you or your child is sitting at that desk feeling like the mountain is too high, I want you to know: that feeling is completely normal, and it absolutely does not have to stay that way.
I've spent years teaching Combined Science to students across the full range — the ones who walk in loving science and just need pointing in the right direction, and the ones who are convinced they "just don't get science" and have more or less given up. What I've found, every single time, is that it's not a lack of ability. It's a lack of clarity. The moment a concept is explained in plain language — with a real reason behind it, not just a definition to copy down — something clicks. And once it clicks, it sticks.
That's exactly what Double Science Decoded is built around. I've taken everything I know about how students actually learn science (as opposed to how they're expected to absorb it) and turned it into short, focused lessons that respect your time and treat you like an intelligent person. No padding. No waffle. No textbook-speak. Just clear explanations, real exam questions, and the kind of mark-scheme insight that usually only comes from having a great teacher in the room.
The dual award is a brilliant qualification — it keeps future options open, it's achievable for the vast majority of students, and with the right preparation, those two grade slots can be something to be genuinely proud of. I built this school because I believe every student deserves preparation that actually works, not just a revision guide gathering dust on a shelf.
If you're ready to approach Combined Science with a real plan, I'd love to be your guide through it. Let's get started.
