Toolkits
Deep dives on the ideas that show up everywhere. Each one starts with why the idea exists at all — the problem it was invented to solve, what it actually does, and where it turns up outside a classroom — and then goes through it properly: the full explanation, the table you actually need, worked examples, and the mistakes that cost marks.
Every unit
Follow the energy
Four units, one accounting problem: energy arrives, changes form, does something useful and ends as heat. The same story at four scales.

Investigation
Predict, observe, conclude
Why the prediction has to come first, how to keep observation separate from explanation, what makes a test fair, and how to write it up so the marks are findable.

How to use these
- Wondering why any of this is a thing? Read the opening section. It is the part a textbook usually skips.
- Stuck on a question type? Open the toolkit for that idea and find the worked example closest to it.
- Revising? Read the tables and try the checks, then go to practice questions to see whether it stuck.
- Revising for a final? There is no diploma exam in Grade 11, so your school sets the exam — the printable worksheets are the closest thing here to sitting one.
