What I teach
Both subjects, all the main exam boards. I specialise in students who are finding the subject hard and need to secure a grade 4 and push on from there, but I also work with students aiming higher.
∑
Maths
KS3 and GCSE Maths (Foundation and Higher, any board). Diagnostic questions to find the misconceptions first, then one idea at a time with visual explanations and plenty of practice.
★
Exam preparation
Past-paper walk-throughs, command words, how marks are actually awarded, and what to do in the last six weeks. I mark GCSE Computer Science papers for OCR, so I know what examiners look for.
How lessons work
Every lesson mixes explanation with doing. Students don’t just watch: they build, trace and test their understanding as they go.
Interactive online activities
Students drag, drop, predict and test code in the browser, so every new idea is practised straight away. Nothing to install.
Try it yourself →Step-by-step scaffolding
Problems are broken into small steps. We trace programs line by line, then take the support away as confidence grows.
Try it yourself →Visual explanations
Abstract ideas such as sorting algorithms, the CPU and logic gates become animations students can see, pause and replay.
Try it yourself →Some of the tools students use
Computer Science
Python Blocks
Students snap blocks together to build real Python, then run it in the browser. The code appears line by line as the program grows.

Computer Science
Flowcharts
Each flowchart shape is explained one step at a time and turned into the matching Python, so design and code stay connected.

Computer Science
SQL Blocks
SELECT, FROM and WHERE become blocks that run against a real database, so students see exactly how each clause changes the results.

Maths
Equations on a balance
An equation becomes a balance scale: do the same to both sides, watch it stay level, and keep going until x is on its own.

Maths
Diagnostic questions
Every wrong answer points to one specific misconception, so we find out exactly what to fix next instead of guessing.

Linked topics open a free interactive activity on this site; the rest are covered in lessons.

How it works
No big upfront blocks. We start small, find out what is actually needed, and you pay session by session.
Free 15-minute call
A short conversation with you and your child about where things are, what the target is and when the exams are.
Baseline check
A short, exam-board-neutral test done at home. It shows me the gaps, and shows us both whether the student is ready to put the work in.
A plan, not a sales pitch
I recommend how many sessions and what we cover. If a few sessions will do it, I will say so.
Pay per session
Card or QR payment via SumUp, or bank transfer for ongoing students. An invoice for every lesson, no contracts.
Why families choose BeanWise
