James was six months out from his external Methods exam, sitting on a C average, and starting to talk like a kid who had quietly given up. His parents got in touch because the gap between how hard he was working and what was actually landing on his report card had stopped making sense.
He had a tutor before us. The tutor was nice. The tutor would explain whichever question James was stuck on, James would nod, and then a week later the same kind of question would catch him out again. Nothing was being rebuilt. Everything was being patched.
The first thing we wanted to know was not "where are you struggling now". It was "where did it last feel easy". For James, that was Methods Unit 1. After that, things started feeling like guesswork.
Three foundation weeks. Then we never looked back.
His tutor, Ben, spent the first two sessions doing a proper diagnostic. Not a worksheet. Actual problems from each unit of the syllabus, with James talking through his working out loud. By session two, the gap was obvious: chain rule. He had memorised the procedure in Year 11 without ever understanding why it was structured the way it was, and that one shaky brick was holding up most of the calculus building above it.
Three sessions were spent rebuilding differentiation from first principles. Limits. Why the chain rule works. Why integration is the inverse. Nothing about exams, nothing about marks. Just the actual mathematics, until James could derive the rule himself rather than recite it.
The rest of the time was past papers under timed conditions, with Ben sitting next to him, watching the working as it was written. The feedback was specific. "You skipped a substitution line. The marker cannot tell if you knew that step." Most students lose marks for things they actually know. Fixing the way he wrote, not the way he thought, was worth almost a full letter grade on its own.
