Why students learn 4x faster on 
Traditional schools advance students by age, not mastery — creating compounding knowledge gaps. We built a system that actually works.
AI tutor that knows you
Every student gets 1:1 AI coaching that adapts in real time. It's what Bloom's 2-Sigma Problem said was impossible to scale — until now.
- Adapts to your learning style and pace
- Explains concepts with worked examples
- Available 24/7 — no scheduling needed
Mastery, not memorization
You advance when you prove you know it — not when the calendar says so. Every concept must be mastered before you move on.
- No moving forward with knowledge gaps
- Retrieval-based assessments, not multiple choice
- Progress tracked at the concept level
2 weeks, not 4 months
Traditional virtual schools drag a single credit over an entire semester. Our students finish in 2-4 weeks because mastery-based learning eliminates wasted time.
- Self-paced — go as fast as you can
- No waiting for the rest of the class
- Average completion: 2 weeks per credit
Accredited from day one
Official OSSD credits issued through our accredited school partner. Same transcript, same credential accepted by every Canadian university — delivered 4x faster.
- Official Ontario Student Transcript (OST)
- Accepted by every Canadian university
- OCT-certified teachers review your work
$250 per credit
Other virtual schools charge $500-600 for the same credit. We cut the price in half without cutting corners.
- Learning is free — pay only for the credit
- No hidden fees or subscriptions
- 57% less than the industry average
Built on learning science
Spaced repetition, retrieval practice, interleaving — every lesson is engineered using techniques proven to maximize retention.
- Spaced repetition to prevent forgetting
- Retrieval practice over passive re-reading
- Interleaved problems for deeper learning
What makes Units different
Every detail is designed to help you learn faster and earn real credits for less.

Assessments that can't be cheated
AI tools are allowed. Encouraged, even. Because if anyone can instantly generate the same output, that output has no value. We assess what AI can't do for you — your thinking, your creative choices, your judgment.
Create
Build something real — a script, a campaign, an op-ed. Use any tool you want. The bar is set above what a prompt alone produces. Default AI output gets you a pass at best. Mastery requires your voice.
Defend
Answer follow-up questions about YOUR work. Why did you make this choice? What would you change for a different audience? AI can't defend decisions it didn't make. Your understanding shows here.
Critique
We show you AI-generated work and ask: what's wrong with it? Can you make it better? If you can't tell the difference between mediocre and excellent, you haven't learned the concept.
Your grade reflects what you know now
A 60 on your first essay and a 95 on your last should not average to a 77. That's not learning — that's accounting. On Units, your grade reflects your current mastery. Early mistakes don't follow you. Projects can be resubmitted. The final assessment lets you prove what you know right now — and that's what counts.
Built on research, not guesswork
In 1984, educational psychologist Benjamin Bloom discovered that students receiving 1-on-1 tutoring outperformed 98% of classroom students. He called it the 2 Sigma Problem — the effect is massive, but personal tutoring doesn't scale. AI changes that.
Immediate feedback
Every answer gets an explanation — not just a checkmark. You understand WHY, not just whether you were right.
Mastery-based progression
You advance when you prove you know it. No moving on with gaps that compound into bigger problems later.
Retrieval practice
Testing yourself is 2x more effective than re-reading. Every concept ends with questions that make you recall, not recognize.
Spaced repetition
Without review, you forget 90% within a week. Units automatically schedules review so every concept sticks permanently.
Worked examples
See how it's done step-by-step before you try it yourself. Reduces cognitive load and builds confidence.
Interleaving
Mixing different types of problems feels harder in the moment but produces deeper, more flexible understanding.

2 weeks instead of 4 months
We don't cut content. We cut waste. The active learning time is the same — what's different is everything around it.
Start at page 1 like everyone else
Adaptive diagnostic skips what you already know
Students routinely skip 20-40% of content on day one
Submit → wait 3-5 days for feedback → revise → wait again
Submit → AI feedback in 10 seconds → revise → resubmit immediately
The feedback loop that takes weeks elsewhere takes minutes
Same pace for everyone, fast students bored, slow students lost
Advance when you prove mastery, not when the calendar says so
If you master it in 3 questions, you move on. If you need 15, you get 15
Review everything on a fixed schedule
Advanced practice implicitly reviews prerequisites
Practicing 'theme' automatically reinforces plot structure, conflict, and characterization
110 hours of 'instructional time' (mostly reading PDFs and waiting)
20-25 hours of 100% active, interactive learning
Every step requires you to think, not just read
Write essays for a teacher no one else will see
Build projects you actually ship to the real world
Students are motivated because the work has real value

Where the “110 hours” actually go
Traditional virtual schools list 110 hours of “instructional time” per course. Here's what that really looks like — and why our students finish the same curriculum in a fraction of the time.
