Scope of work & boundaries
Clear expectations on what is covered and what this does not include.
The 25-minute free diagnostic
We work through three carefully selected problems together. David observes how the student annotates questions, handles dead ends, and explains their reasoning—identifying exact conceptual hurdles without pressure.
Transparent 4-week reviews
We do not lock families into long contracts. Every four weeks, we review topic progress against exam mark schemes so parents and students clearly see tangible gains in working fluency.
Interactive digital whiteboard
Online students receive a shared digital board with full session notes exported as a PDF immediately after every lesson, building a personal revision notebook.
Reasoning over formula memorisation
Exam boards penalise memorised answers applied blindly. We focus on why methods work, ensuring unfamiliar questions in the exam hall do not cause panic.
