From a lesson to a marked answer
Learn the idea
Short chapter videos built from the basics, in 720p or a lighter 480p.
Practise and see the mistake
Each wrong quiz option exposes one misconception, so a wrong answer tells you which idea to fix.
Example: you pick “the car weighs less on the Moon, so its mass changes”. The explanation shows that weight changes and mass does not.
Write it on paper, photograph it
Answer by hand, upload a photo. It is marked point by point, and every missed point says what was missing.
See where the marks went
Results by chapter and topic, the habit that keeps costing you marks, and a predicted grade once you have answered enough.
