How Lumini helps with GCSE Maths
You're looking at a GCSE Maths past paper on your Mac — maybe a PDF from your school, a page on Maths Genie, or a Corbettmaths worksheet. You hit a question you can't solve. It's a trigonometry problem, a quadratic equation, or one of those vector geometry questions that always trip you up.
Normally you'd open YouTube, search for a walkthrough, skip to the right timestamp, watch someone solve a similar (but not identical) problem, and try to map their solution to your question. This takes 5-10 minutes per question. Over a full past paper, you lose an hour just switching tabs.
Lumini changes this. Hold Ctrl+Option and say "How do I solve question 14?" or "I don't understand what this question is asking." Lumini sees your exact past paper — the diagram, the numbers, the marks available — and walks you through the solution. It explains the method, not just the answer. It points at the diagram when referencing angles or lengths. It tells you how many marks each step is worth and what the examiner is looking for.
Tutor mode for Maths revision
Turn on Tutor mode while working through past papers. After you attempt a question and pause, Lumini checks your working. "You've got the right method but check your signs — negative times negative gives positive. I'm pointing at the line where the error is." This immediate feedback means you learn from every mistake instead of practising errors.
When Tutor mode sees you struggling with the same topic across multiple papers — say, you keep getting circle theorems wrong — it notices the pattern. "You've missed three circle theorem questions in a row. Let me explain the alternate segment theorem — it's the one that comes up most often in exams. I'll point at the relevant angles in your diagram."
Example questions to ask Lumini
- "How do I complete the square for this quadratic?"
- "What's the formula for the area of this shape?"
- "Why does my answer not match the mark scheme?"
- "How many marks would I get for this working?"
- "Is there a quicker way to solve this without expanding everything?"
- "What topic is this question testing?"
How Lumini automates your revision
Say "Create a note with the formulas I need for the non-calculator paper." Say "Remind me to do a past paper at 10am tomorrow." Say "Search the web for GCSE Maths predicted papers 2026." All while staying on your past paper. No tab switching, no broken focus.
