I Teach
Professional tutoring that goes beyond just passing exams. I help students build confidence, master logic, and develop the study skills needed for lifelong success.

Hi, I'm Joshua.
I am a First Class Mathematics graduate from Durham University, currently working as a Technical Consultant in London. Alongside my professional career, I founded JCollierTutoring - bringing the same analytical thinking and problem-solving I use every day in industry directly into my sessions with students.
Why Do I Tutor?
I didn't have a tutor during my A-Levels, so I had to learn the hard way that intelligence isn't about understanding things instantly, it's about persistence. Now, I want to be the mentor I wish I had.
I don't see students as just voices behind a screen. I pride myself on being a listener first and a teacher second. My goal is to move beyond just "hacking" the mark scheme; I help you master the underlying logic so you can answer any question confidently.
Problem Solver
I don't just teach you to memorise formulas. I teach you how to think like a mathematician and a programmer. We focus on the "why", not just the "how".
Academic Excellence
With a First Class Honours from Durham University and A*A*A*A at A-Level, I've walked the path you're on and I know exactly what it takes to excel.
Modern Methods
Using Google Meet and interactive virtual whiteboards, I provide online lessons that are as effective as in-person sessions.
