Original unit tests, worksheets, and quizzes for grade 11 and 12 Ontario high school courses — organized the way you'd expect a course to be organized: by unit, with a test at the end of each one.
Drag sliders, plot points, and watch graphs update live — the same demo you just tried above shows up throughout every lesson.
A daily streak and XP system built to make five minutes of practice a habit, not a chore.
Daily Review resurfaces exactly the questions you're close to forgetting, using the same idea behind flashcard apps like Anki.
Every course is organized the way your class actually is — by unit, with worksheets building up to a proper unit test.
Find your exact course by grade and stream — from MCR3U to MHF4U and beyond.
Interactive lessons and worksheets that build up gradually, unit by unit.
Check what you actually know before the real one — track XP and streaks along the way.
Premium is a nice-to-have for students who want extra support and personalization — it's never required to learn the material. Nothing that helps you actually pass a unit test lives behind a paywall.
Everything you need to actually learn the course.
For students who want a bit more polish and support around the free experience.
"I finally have a place that's organized the same way my actual class is — unit by unit, with a real test at the end."
"The streak thing is dumb but it works — I've done Daily Review every day for three weeks now."
"Didn't pay for anything and still got through the whole unit test prep. Premium's there if you want it, not if you need it."
No. Every course, lesson, worksheet, and unit test is free to complete online for every signed-in student, permanently. The only limit on the free plan is downloading/printing PDF copies of unit tests, capped at 5 — taking them on-screen is always unlimited. Premium removes that download cap and adds a few other extras, but never gates actual course content.
Grade 11 and 12 Ontario high school courses, University and Mixed streams, organized unit by unit the way your class actually runs.
Yes — educators get their own sign-in with class analytics and the ability to assign content, separate from the student experience.
Yes, the whole platform is responsive and works in any modern mobile browser — no app install required.
Pick a base function, then transform it with sliders or by typing values directly. Watch the equation and graph update live — including automatic arrows and asymptotes.
Set up a domain or range restriction below, then build the matching notation out of tiles — just like the notation builder inside a lesson, but with settings you control.
