Press Next step (or → / Space) to reveal the next part of a topic. When you reach a Your turn, tap it to open the question. The examples above blur so you can't copy them. Work it out before you press Next step for the answer.
- ⚑ Got it wrong flags an answer (drag it onto one part to flag only that part). Flags collect in the To redo bar at the top.
- Low / Med / High marks a concept to come back to. They collect in My review.
- ✎ Note keeps your own note, ✎ Edit asks AI to rewrite the block, Copy copies it as an image.
- Select any text and tap the clip to ask AI about it.
Every Your turn and practice question has ✎ Work it out. Pen, eraser and highlighter change size when you drag sideways on the button, and holding a button opens its colour wheel.
- Check: box one step and AI checks only that.
- Calc: box a sum and see its value in a bubble that disappears when you tap it.
- Mark: line-by-line marking with pins on your working. ✗ means a critical error, ⚠ a slip, ↳ an error carried forward, and the "?" on a row explains that mistake.
Each topic ends with Practice: AI writes new exam-style questions aimed at what you flagged and marked. Use the arrow in the topic list to add your own practice tabs.
Give AI this page and your study guide, past papers and memos, then ask: "Fill this revision pack template for <module>: one unit per study unit, lessons with Your turn questions and answers, a cheat sheet per unit, a definitions drill and a timed mock from the past papers."
At the top of the file, the pack-config block holds the settings:
- Title and the line above it.
- Module, exam name and exam rules (e.g. "no calculator").
- Who is studying, and their level.
- The kind of tutor AI should be.
- The question style.
- Recurring slips for AI to watch for.
- A storage key. Use a different key per module.
AI's marking, checking, practice and explanations all use these settings.
Each topic is one <section class="chapter">. Its data-group is the unit it appears under in the left list, data-title is its name, and id must be unique.
Each <div class="step"> inside the topic is one click. The comment above the first section lists the step types: plain, rule, watch, turn and answer.
Give a unit's summary topic an id that ends in -cheat. AI then uses it as context for that unit's practice and explanations.
For definitions, pair a Your turn ("Define …") with an Answer. For a mock exam, put the questions in Your turn steps with their marks in the tag.
Keep the My review section (id="x-marked") as it is: the marked-concepts list is built there. Delete the example unit once your own topics are in.
A percentage change compares the change with the starting value, not with the new one.
A price rises from R80 to R100.
\[ \frac{\color{#ea7c0c}{100-80}}{\color{#3b82f6}{80}}\times100\%=\frac{20}{80}\times100\%=25\% \]Dividing by the new value gives \(\frac{20}{100}=20\%\), which is wrong. Always divide by where you started.
A town's population falls from 2 500 to 2 000. Find the percentage change.
A 20% decrease. Marks: formula with the old value (1), substitution (1), answer with a sign or the word "decrease" (1).
Percentage change
\(\frac{\text{new}-\text{old}}{\text{old}}\times100\%\). Negative means a decrease.
Your second fact
One card per formula, rule or method.
Your third fact
Keep each card to two lines.
Each term appears first. Say or write the definition, then click to check it word for word against your study guide.
Percentage change.
The change in a quantity expressed as a percentage of its original value.
Set a timer and work under exam conditions. Tap each question to open it, and only press Next step for the answer when time is up. Put real past-paper questions here, with their marks in the tag.
A R1 200 item is reduced by 15% and then increased by 15%. Find the final price, and explain why it is not R1 200.
\(1200\times0.85=1020\), then \(1020\times1.15=1173\). The final price is R1 173. The 15% increase is taken of the smaller amount (R1 020), so it adds back less than the R180 that was taken off.
Nothing marked yet. Tap Low, Med or High on any step you want to come back to, and it will appear here.
