Eloane’s mother — Première student, maths specialty: “Sullyvan knows his subject very well. He is patient with my daughter and takes the time to re-explain lessons and exercises when she doesn’t understand. He is always on time and polite. I recommend him.”

Clément — Terminale student who went from 5 to 20: “Sullyvan truly changed the way I see this subject. He helped me regain confidence step by step, showing me that my efforts mattered and that it was fine to take my time. Today I feel much more comfortable with maths, and it is largely thanks to him.”

Nassim’s brother — 1st-year TSI prépa student: “Sullyvan identified his gaps and re-explained concepts and exercises. He shared valuable resources (revision sheets and Anki). His prépa-tailored follow-up was a great help with organisation and method. Nassim made a lot of progress and regained confidence. The online lessons are a real plus!”

Achille — 2nd-year ECG prépa student, Applied Mathematics: “I recommend Sullyvan, who helped me a lot and still helps me today to catch up and improve. The lessons are very well explained and the video calls help a lot.”

Jeanne — member of my study group in first year at Ginette: “In prépa, Sullyvan supported me in mathematics. Very rigorous, his explanations were always clear and well structured. When we did not understand, he kindly took the time to re-explain the lessons several times.”

Valentin — member of my study group in his third year (khube) at Ginette: “Sullyvan helped me truly understand maths in prépa! After two years of struggling with the subject, his teaching and choice of exercises took me to the top. Thanks to him I went from 10 to 18 in maths, which got me into HEC despite the penalty for third-year students!”

Martin — prépa friend I prepared the entrance exams with: “Sullyvan’s rigour and teaching helped me make great progress during my second year of prépa. The oral practice paid off: I got into ESCP this year with 18/20 in the oral!”
