RAG stands for 🔴 Red, 🟡 Amber, 🟢 Green: a way to track your confidence on every spec point.
You can manually change any flag by clicking the button on a spec point. Your Review page shows only Red and Amber items, so you can focus on what actually needs attention.
When you complete a quiz at the end of a spec point:
This automatic flagging helps you quickly see which topics need more revision without manually marking everything yourself.
Absolutely. Every spec point has RAG buttons above the notes. Click them to manually set Red, Amber, or Green at any time. This is useful if you want to mark something as Green because you're confident from other revision, or if you want to re-flag something as Red to focus on it later.
The Review page is your personal revision checklist. It shows:
The goal is simple: work through the Review page until everything is Green. Once you've reviewed every flagged point and moved them all to Green, you've covered everything in the spec.
Yes. After you complete a quiz, you'll see a "Retake quiz" button. Click it to answer the same questions again. Your new performance will update your flag, so if you do better the second time, your RAG status will change accordingly.
Learn page: The full course. All 5 topics, all subtopics, all spec points in order. Use this to work through the spec systematically.
Review page: Your flagged items only. Use this to focus revision on gaps. You can sort by topic, or just work through the list in order.
Yes, 100%. We cover every spec point for Edexcel iGCSE Biology (4BI1), organised into 5 topics with subtopics and individual points. Nothing is left out, and nothing unnecessary is added. If it's in the spec, it's here. If it's not in the spec, it's not here.
The course is split into:
The 7 Core Practicals are specific experiments that Edexcel requires you to know for your exam. Each one is broken down using the CORMS framework:
You can access all 7 practicals in the sidebar under "Core Practicals".
Yes. The notes cover exactly what the exam expects, no more, no less. They're written specifically to match the spec points, so if you understand everything in Bare Bones Biology, you'll have what you need for the exam. That said, they're bare bones on purpose: concise and focused, not rambling textbooks.
Not currently. The notes are read-only. But you can use the Review page to flag areas you want to revise further, then add your own notes elsewhere (in a notebook, digital notes app, etc.) and come back to the flag in Bare Bones Biology to track your progress.
Not in the main course. However, you can link external resources (like YouTube videos or textbook chapters) to individual spec points if you want to supplement your revision. These links are saved in your account so they're always there when you need them.
Yes. When you log in, all your RAG flags, quiz results, and review items are stored in the cloud. You can log in from any device and see your exact progress. Your desktop, tablet, or phone will all show the same flags and scores.
Your progress is saved to your account in the cloud, so it's safe. When you log back in (on any device), you'll see all your flags and quiz results exactly as you left them.
Yes. In the Learn page, you can reset your progress for a single subtopic or clear everything at once (all RAG flags, quiz results, etc.). This is useful if you want to start fresh or redo a whole topic.
Absolutely. Bare Bones Biology works on phones, tablets, and desktops. Study on your phone during breaks, switch to a laptop at home. Your progress syncs across all devices.
Yes, you need an internet connection to log in, save progress, and sync your flags. However, once a page has loaded, some parts (like reading notes) may work offline for a short while.

Here's the recommended workflow:
It depends on your starting point and how much time you spend. Working through the course thoroughly (reading notes, taking quizzes, revisiting weak areas) typically takes 40–60 hours. But you can work at your own pace. Some students use it for 2–3 months of focused revision; others spread it across their whole iGCSE course.
When you choose a wrong answer, the quiz shows you the correct answer and tells you to check the notes. Go back to the notes, re-read the relevant section, and then retake the quiz. This reinforces learning and helps you move from Red/Amber to Green.
Both strategies work:
Many students do a first pass by topic, then a second pass focusing on Review items.
The quizzes are multiple-choice and test the specific concepts in each spec point, similar in style to Edexcel exams. However, they're not full past papers. Use Bare Bones Biology to learn and understand the spec, then practice with real Edexcel papers (which your school will provide) before the actual exam.
Bare Bones Biology is built for Edexcel iGCSE Biology (4BI1) specifically. If you're studying a different exam board (AQA, OCR, etc.), the core content overlaps significantly, but some details may differ. We recommend using this as a supplement to your exam board's materials rather than your only resource.
Bare Bones Biology covers all the spec content you need. Whether you get a good grade depends on how thoroughly you learn and understand the material, and how well you apply it in the exam. The system is designed to help you revise effectively, but ultimately, getting a top grade requires effort, engagement, and exam technique, which comes from practice papers and your teacher's support.
