What people are saying
It’s already clicking for learners and parents
Real comments from students and parents on our YouTube lessons — the same explanations behind every worksheet and paper here.
“Honestly, this is the first time fractions have actually made sense to me. I've watched a few other videos but they always seemed to skip steps or assume you already knew what was going on. The way you explain everything from the basics without talking down to people is brilliant. Really hope you keep making more KS3 videos because they're helping me loads.”
“Found this by chance while helping my daughter with her KS3 homework, and I'm so glad I did. The explanations are calm, well structured and easy to understand, with plenty of examples that gradually get harder. She went from saying she hated fractions to confidently answering the questions on her own. We'll definitely be coming back for the rest of the series.”
“I'm in Year 8 and we've just started percentages. I watched this the evening before my maths test because I was completely stuck, and it finally clicked. I even went back and watched your decimals video afterwards because it was explained in exactly the same simple way. These videos are honestly better than a lot of the revision websites I've used.”
“Brilliant explanation. Clear, easy to follow and straight to the point.”
“Thank you. The pace is perfect and I love that you don't skip any of the working out.”
