- Practice tests on request in three modes (balanced, focused on the hard skills, manual pick) and simulations on request
(all the material, timed, no choice, repeatable). No plan, no window, no one-time rule. Old exercise tests 1-2 count as balanced, 3 as focused.
- Readiness moves only with handed-in tests, only up: number += GAIN x (grade - number), GAIN 0.6 simulation, 0.3 practice,
0.15 manual. Mastery and deepening no longer count. Levels, points to the next level, what a perfect test adds.
- Home: one compact block (number, level, days left; practice and simulation buttons with +N), still one screen.
The test page: how it goes up, simulation, practice modes, the trail of gains. A result opens with its gain and a level up.
- Teacher tabs show readiness, test counts and bests. countdown.py removed. OpenSpec change tests-on-demand; PRD updated.
