Plans
You’re not buying lessons. You’re buying a system that learns you.
DSE finds your gaps, plans your next step, and adapts until you can prove — with real evidence — that you’ve closed them. Start free. Upgrade when you’re ready. Cancel anytime.
What you get on every plan
Every plan runs the same learning system — on the courses that plan unlocks.
Find your gaps
A real diagnostic locates what you don’t know yet — no score you didn’t earn.
Next Best Action
One clear next step, chosen from your real evidence — not a fixed syllabus order.
Adaptive practice
Questions target your gaps and adjust as the evidence changes.
Mistake repair
When you miss, you get the fix — then an unseen re-test to prove it stuck.
Demonstrated mastery
Shown only from unaided, correct work. Reading a lesson never counts as mastery.
Daily learning plan
A short, honest plan for the time you have — 10, 30 or 60 minutes.
Exam Mode
AP coursesFull exam simulations that shift your practice toward the real test as it nears.
Mistake Notebook
AP coursesEvery mistake collected, explained and brought back until it’s fixed.
Course Rank
AP coursesThe same weekly challenge for everyone — marks for difficulty and first-try accuracy, never volume.
We don’t promise marks or grades — no honest system can. We show you the highest-value work and real proof of what you’ve mastered; the outcome is your effort. The adaptive engine is live on our Math and AP courses today and expanding to every course.

Questions
Why don’t you advertise a question count?
Because a big number of questions isn’t learning. DSE serves the right question for your gap, then proves you’ve closed it with an unseen re-test — you’re paying for the system that decides that, not for volume.
Do you guarantee better marks?
No — no honest system can. We show you the highest-value work and real, unaided evidence of what you’ve mastered. The result depends on your effort.
Can I cancel anytime?
Yes — manage or cancel your plan from your account. Access continues to the end of the billing period.
Can I switch plans?
Absolutely. Upgrade or downgrade whenever you like; changes take effect at your next renewal.
Is my payment secure?
Payments are handled by Stripe. We never store card details.
Curriculum-aligned learning support — not an official school, university, or ministry-approved course, and not a replacement for official credit.
