For BC Grade 11–12 Math & Science · AP
Studying more isn't the answer.
Studying the right thing is.
DSE finds the exact concepts holding you back, teaches them deeply, adapts your practice, repairs your mistakes, and proves you're ready — before exam day.
11 courses live today, with 360+ deep lessons. No card to start.
- Spec-drawn
- Figures, their captions and their alt text are generated from one figure spec.
- Reviewed
- A lesson shows the date it was last reviewed, and shows no date when there is none.
- Traceable
- Mastery is computed only from questions you have answered, never from pages read.

Start with a real check
A short diagnostic, then the single best place to start.
Twelve original questions — one per skill. At the end you get an honest per-skill profile and the exact topic to fix first. You never see a score you didn't earn.
Take the diagnosticQuadratic equations
Solve x² − 5x + 6 = 0 and give the larger root.
At the end: your honest profile (example)
No score you didn't earn — the check shows the single best place to start.
Find the gap. Fix it. Master it.
Most tools give you more to do. This one figures out what to do next.
- 01DiagnoseFind the exact skill causing the difficulty — not the chapter, the skill.
- 02UnderstandLearn it through explanations, derivations, worked examples and visual reasoning.
- 03AdaptPractice changes with demonstrated performance — harder when you are ready, easier when you are not.
- 04FixA wrong answer becomes targeted remediation for the misconception behind it.
- 05ProveSolve new, unseen problems independently before mastery is awarded.
What you can learn
Built from real teaching experience
“After years of one-to-one teaching, the same pattern kept showing up: students weren't short on ability — they had specific conceptual gaps that had built up over time. Find the gap, rebuild the concept from first principles, raise the difficulty, and keep testing until they can solve unfamiliar problems on their own. That process is the platform.”
Four things that make it stick.
Derived, not dictated
Every rule is built from where it comes from, so you can rebuild it under exam pressure.
Progress is not mastery
Reading a lesson or watching a video never counts as mastery — only solving unseen problems does.
A person checks the work
Send a question or your written solution and a qualified teacher reviews the reasoning, not just an automated key.
Original, verified questions
Every question is written for DSE and checked programmatically — nothing lifted from a textbook.

Questions, answered honestly.
Who is DSE for?
BC Grade 11–12 students in Math, Chemistry, Physics and Biology, and students taking AP Chemistry or AP Calculus.
Will it improve my marks?
We can’t promise a grade — no honest tool can. We find your exact gaps and prove mastery from real, unaided work; the result depends on your effort.
Is it free to start?
Yes. The diagnostic and one complete learning loop are free, no card needed. Paid plans unlock full courses.
How is this different from other apps?
It decides what to study next from your own evidence. Reading a lesson never counts as mastery — only solving new, unseen problems on your own does.
Are the questions copied from textbooks?
No. Every question is original to DSE and verified programmatically before you ever see it.
Find the gap that's costing you marks.
