Why Modilix

Learning that responds to you, not the other way around

🎛️

Interactive, not just readable

Drag sliders, plot points, and watch graphs update live — the same demo you just tried above shows up throughout every lesson.

🔥

Streaks that keep you consistent

A daily streak and XP system built to make five minutes of practice a habit, not a chore.

🧠

Spaced review, built in

Daily Review resurfaces exactly the questions you're close to forgetting, using the same idea behind flashcard apps like Anki.

📊

Real unit structure

Every course is organized the way your class actually is — by unit, with worksheets building up to a proper unit test.

How it works

Three steps to your next unit test

1

Sign in & pick your course

Find your exact course by grade and stream — from MCR3U to MHF4U and beyond.

2

Work through the unit

Interactive lessons and worksheets that build up gradually, unit by unit.

3

Take the unit test

Check what you actually know before the real one — track XP and streaks along the way.

Free vs. Premium

Every lesson, every unit test — free. Always.

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.

Free

$0/forever

  • ✅ Every lesson, worksheet & unit test — take them online, unlimited

Students say

Built with the way real students actually study

"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."

— Grade 11 Functions student

"The streak thing is dumb but it works — I've done Daily Review every day for three weeks now."

— Grade 12 Advanced Functions student

"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."

— Grade 11 student
Questions

Good to know

Do I need Premium to use Modilix?

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.

What courses are covered?

Grade 11 and 12 Ontario high school courses, University and Mixed streams, organized unit by unit the way your class actually runs.

Is this made for teachers too?

Yes — educators get their own sign-in with class analytics and the ability to assign content, separate from the student experience.

Can I use this on my phone?

Yes, the whole platform is responsive and works in any modern mobile browser — no app install required.
