11+ tutoring shouldn't cost £50/hour.
My kid's preparing for the 11+ exam. I looked into tutoring: £40-80/hour. Practice books: £15 each and you run out fast.
So I built something instead.
11+ Tutor - free, open-source exam prep:
- 1,364 verified questions
- Verbal Reasoning, Maths, NVR, English
- Instant feedback with explanations
- Runs entirely on your computer (no data sent anywhere)
All questions are programmatically verified or validated against curated word lists. Wrong answers are fixed within hours of being reported.
Features:
- Topic lessons before practice
- Strategy guides for each question type
- Timed mock exams
- Printable worksheets
- Optional AI tutor (local LLM)
It's MIT licensed. Free forever.
If you're preparing a child for grammar school entrance, this might help.

I built a free 11+ exam prep tool. Here's why.
The 11+ is a high-stakes exam for 10-year-olds. Pass it, you might get into a grammar school. Fail it, and that door closes.
The problem: preparation costs money. A lot of it.
- Tutors: £40-80/hour
- Practice books: £10-15 each (you need many)
- Online courses: £200-500
Kids from wealthier families get more practice. That's not fair.
So I built 11+ Tutor:
✅ 1,364 questions (VR, Maths, NVR, English) ✅ All answers verified programmatically or validated ✅ Strategy guides and worked examples ✅ Printable worksheets for offline practice ✅ Mock exams with timing ✅ Runs locally - no data collection ✅ MIT License - free forever
The questions are generated by algorithms (maths, sequences) or from curated word lists (synonyms, antonyms). No LLM hallucinations. No wrong answers.
Question quality matters more than quantity. A tool with wrong answers is worse than no tool at all. Every question passes automated validation.
If you find a bug, report it. It gets fixed same day.
This won't replace a good tutor. But it gives every family unlimited free practice.

Building an exam prep tool with guaranteed correct answers
LLMs are great at many things. Generating exam questions with verifiably correct answers? Not one of them.
So for 11+ Tutor, I took a different approach:
Programmatic generation for questions where answers can be computed:
- Number sequences (arithmetic/quadratic patterns)
- Letter pattern sequences
- Arithmetic calculations
- SVG-based visual reasoning (NVR)
Template + validation for word-based questions:
- Synonyms/antonyms validated against 200+ curated word pairs
- Hidden words verified by string matching
- Compound words from verified list
Curated content for reading:
- Aesop's Fables (public domain, age-appropriate)
- Hand-written comprehension questions
Result: 1,364 questions, 57 automated tests, all passing.
The test harness validates:
- Question structure
- SVG rendering
- Answer submission (correct & incorrect)
- API responses
Stack: FastAPI + Next.js + SQLite + SVG generation
