About William
I'm a Computer Science student with over 10 years of programming experience, having worked at IBM and as a university researcher, but what keeps me in the subject is simple: I love it. There's something incredibly satisfying about the moment when a concept clicks, and helping students get there is what tutoring is all about for me.
I've mentored colleagues and peers throughout my time at IBM and university, so I know that the best way to help someone understand CS isn't to talk at them — it's to ask the right questions and let them find the answer themselves. Computer Science is all about foundations, each topic builds on the last, so building a true understanding of a topic is more important than other subjects. The Socratic approach that I use builds these foundations, students don't just memorise content, they actually think like a programmer or computer scientist, which is exactly what separates strong exam performances from average ones.
Whether you're working through GCSE algorithms or tackling A-Level theory and programming projects, I'll meet you where you are, figure out where the gaps are, and help you build understanding that holds up when it matters most.

Every student is different, so I start by looking at where you actually are by working through a past paper or recent classwork together to pinpoint the gaps in your understanding. No guessing, no generic curriculum, just targeted work on what will make the biggest difference to your grade.
From there, lessons blend concept discussion, worked examples, and most importantly — building things.
Professionally, I've always operated by a simple principle: if you can't build it, you don't understand it. Reading textbooks or copying notes creates surface-level familiarity, an all-too-common strategy for students that doesn't hold up on exam day. Writing code and solving problems forces real understanding, so where possible we will apply concepts hands on, because that's what makes them stick.
For trickier theory, we'll use diagrams and walkthroughs to make abstract ideas concrete before we put them into practice. Throughout, rather than handing you the answer, expect questions that guide you to it yourself. Questioning and finding gaps in your understanding is exactly how the best CS researchers work, and it holds true for learning Computer Science too.
Sessions can be online or in-person, and I'm always happy to work around whatever you bring on the day.

I met Will at university and coming from a Law background I was always scared by the thought of learning programming.
Will taught me basic python in a few hours through hands on exercises, building a calculator. This approach worked really well for me and I now feel confident writing python programsView more recommendations
