Chapter One · The Practice Lab
Fifteen thousand items, three hundred and ninety-three exams, three subjects. Every question carries its source contest, page, and topic taxonomy. Nothing is paraphrased; the wording you see is the wording your student will see at Regionals.
Coaches see one roster, scored and sorted. Spaced repetition runs underneath, surfacing the topic a student is about to forget at exactly the moment they would have. The work disappears into the rhythm of a contest season.

The practice loop, the tuning loop, the spaced-review loop, the coach loop. Each runs on the same question bank and the same topic taxonomy. Students see one inbox; coaches see one roster; the contest sees a prepared team.
Six modes, mixed, timed, weak-spot, speed drill, night-before, review. Every answer feeds the spaced-repetition queue and the coach's exception inbox.
Questions land where you actually learn. The lab calibrates after every answer so the next one sits in the zone where accuracy and progress balance.
The queue surfaces the question a student is about to forget at exactly the moment they would have forgotten it. No flashcards to maintain.
One roster, scored and sorted. Assignment building, weak-spot inboxes, contest-week diagnostics, and access codes that move with a roster across semesters.
No account, no score kept — one real question from the bank, with the contest it came from. Pick an answer to reveal the solution.
In the reaction 2H₂ + O₂ → 2H₂O, if 4.0 mol of H₂ react with excess O₂, how many moles of H₂O are produced?
The left pane is the kind of loose paraphrase a competitor might show. The right is the exact UIL wording — subscripts, capitalization, and all. Drag the seam, or focus it and use the arrow keys.
Determine the pH of a 1.0 × 10⁻² M HCl solution.
If you dissolve a strong acid to make a hundredth-molar hydrochloric acid solution, what is its pH?
Nothing is paraphrased.
A field-day count, a predicted Regional score, a specimen cabinet, and a roster that travels week to week — opt-in, anonymized handles, never a public ranking. Hover a row to read its rhythm.
Every leaf topic in the UIL Science taxonomy, one cell each, colored by subject. The bank carries every contest tier, from Invitational to State.
You’ve seen the cabinet, the bank, the coach’s roster, and one of the questions. Open a notebook to keep going — free, ten a day, forever.
