Maths is learned by practice not by watching one more video
Every skill in limits, derivatives and integration has a question generator: the numbers change on every attempt, so no answer is memorised and no question repeats. The score says when the skill is mastered and when it comes back.

Skill, generator, score — not course and video
The unit here is a single skill practised until it is mastered, and what practice leaves behind is a number you can read, not hours counted.
Parametric question generator
Each skill is a template with constraints, and the question is built on request in the browser. Two attempts, two questions.
Mastery score
It rises with a correct answer and falls with a wrong one, so it says where the learner actually stands.
Content follows your course
Every skill and category belongs to a course, and a learner sees only their own — not one list for every course.
Weekly report — optional
If your account has a guardian linked, your week reaches them by email on a private link: what was mastered and what needs another pass.

The booklets the platform started from
Calculus lecture notes and problem sets prepared for METU students, free to read in full with no sign-up. The platform's skills come from the same material: what you read in the booklet you practise with questions generated on every attempt.

Practise
The question is generated in your browser, and marking comes after each answer, not at the end of a test.
Master it
The score says when the skill is mastered; anything below comes back next session.
