Why Maths feels hard
Four reasons capable students get stuck at Grades 4–6
None of them mean your child isn't good at Maths.
02
They're Losing Marks They Could Be Winning
They understand the Maths but don't show the method examiners expect. We teach them to structure working and tackle unfamiliar questions.
03
Their Revision Has No Clear Direction
Hard work goes on familiar topics while the ones costing marks get avoided. We give every week of revision a clear purpose.
04
Confidence and Motivation Are Disappearing
Repeated mistakes can convince capable students they're "just not a Maths person". Steady progress rebuilds their belief.

Meet your tutor
Hi, I'm Victoria
"Just as a strong stem supports a plant's growth, strong Maths foundations support a student's confidence, progress and future."
I've taught since 1991 and tutored in the UK since 2015. Again and again I've seen capable students stuck at Grades 4–6: working hard, but with gaps in their core knowledge and little confidence in exams. I created StemCore to give Year 10 and 11 students the structured teaching, targeted practice and feedback they need to break through.
