11+ maths · London
I took my own children through the London 11+. Two tutors, four years of papers, and a lot of evenings spent working out how the answer was actually meant to be reached.
The answer papers are free. What I sell is the part nobody else writes down, which is what the whole thing costs and which deadlines close a year early.
Worked example · ratio
A recipe uses flour and butter in the ratio 5 to 2. If 350 g of flour is used, how much butter is needed?
140 g of butter
The step most children skip is finding one part. Teach that move and half the ratio questions in an 11+ paper stop being hard.
Four St Paul's Girls' School sample papers with the answers filled in. Not a teaching guide, just the answers, so you can mark a paper in ten minutes instead of working every question out yourself at nine at night.
Subscribe and the download links arrive straight away. You also get the blog, which is roughly every other week and mostly about what this whole process actually costs.
Free. Unsubscribe any time. I don't share addresses with anyone.
One more click on Substack to confirm, then the four papers arrive by email. If the box above misbehaves, subscribe here instead.
Each guide is a PDF plus a working spreadsheet you fill in with your own shortlist. You download them and keep them. Nothing is a subscription and nothing expires. Buy the one that matches your situation, not both, because the overlap is large.

Tell me when it's outI'm a mum of two in London and a writer. I'm not a maths teacher, which is rather the point. I came to all of this the way you probably have, as a parent holding a past paper at nine in the evening with no idea how the mark scheme got from the question to the answer.
So I worked them out, paper after paper, for four years. The answers I filled in along the way are on this site for nothing, because a marked paper at nine in the evening is worth more than another workbook.
The answers are free because answers are the easy part and plenty of people give them away. What took me four years to learn was everything around them, and that's what the guides are.
The question papers belong to the schools and I give them away exactly as they publish them, with my answers added. I have never sold one and I never will. What I sell is the guides, which are mine.
