aesoptutor
An adaptive study system for school coursework and Advanced Placement examinations.
Mastery scale
Each tier carries a shape, a filled position and a label as well as a colour, so it reads without colour vision. Luminance moves monotonically across the five, so the progression also survives greyscale.
- Untested
- Taught, not demonstrated
- Developing
- Proficient
- Exam-ready
Controls
Used to sign in. You can change it later.
Enter a year between 2026 and 2030.
Overlays
One implementation. Both trap focus, close on Escape, restore focus to the control that opened them, and lock the page behind.
Accessibility preferences
Everything defaults to your system setting. The override exists because a shared machine is one where the system setting is not yours to change.
