About Lenny
Mathematics is my passion, and nothing makes me happier than the moment a student finally understands what had been holding them back.
I taught for five years in state schools, then the British curriculum in a British school. Today I teach the IB (Analysis and Approaches, SL and HL) and French Baccalauréat math at an international boarding school in Switzerland, where I also supervise Internal Assessments and Extended Essays. I know from the inside what examiners expect, line by line.
I am also the creator of Hence, a website I built so that good mathematics is open to everyone, wherever they study and whatever their budget. Everything on it is free, with no sign-up and no ads:
– courses, exam-style questions and markschemes written and checked by me;
– interactive tools to learn to think like an examiner and to master the calculator;
– the stories of the mathematicians behind the ideas.
I add to it every week, and every mistake a student reports is corrected for everyone. If something helps one student understand, it should help them all.
Patient, demanding and enthusiastic, I adapt to each student’s pace and goals, and I make sure every lesson leaves you more confident than before. Search “Hence math” to see how I teach before we even meet.

Whether you are struggling or aiming for a 7, every lesson is built around you.
How we work together:
– we pinpoint exactly what is holding you back, without judgement;
– we rebuild each idea from its roots, until it makes sense;
– we practise on real exam-style questions, with the markscheme line by line;
– we prepare for the papers with a method: timing, writing that earns marks, the calculator;
– for the IB, I also guide your Internal Assessment and Extended Essay, from choosing the topic to the final draft.
Between lessons, you are never on your own. Everything I create is free on my website, Hence, with no sign-up and no ads:
– clear courses, with figures that move;
– exam-style questions with full markschemes;
– Mark it: learn to mark your own answers like an examiner;
– GDC training: every Paper 2 calculator move, key by key;
– the Exam room: build a paper that fits you, sit it, and get it marked;
– an interactive timeline of the history of mathematics.
Search “Hence maths” on Google, try it, and keep whatever helps you. Then write to me and tell me where you are: I always reply.
