Why HKDSE Students Are Switching to SketchMath
Most HKDSE AI tools bolt a chatbot or auto-marker onto static content. Some spread across every subject and curriculum — HKDSE, IGCSE, A-Level, and IB — so their DSE Math stays broad rather than deep, and explanations lean on text and auto-marking instead of visuals. Others go deep on the DSE marking scheme itself, tracking real M-marks and A-marks — but a locus, a 3D solid, or a transformation problem is still just words and numbers on a page.
SketchMath combines both: the same DSE marking-scheme accuracy your teacher would recognize, benchmarked at 98.5%, wrapped in interactive GeoGebra visuals your child can drag, rotate, and explore. Your child doesn’t just get an answer — they see why it’s right. And it’s free to start.
