Practice that matches your lessons, day by day
Match the course, unit, and day to the handout. Students work through Guided, then Easy, Medium, Hard, and Boss as assigned. You choose the daily goal; generated problems vary the numbers for further practice.
- Instant feedback with non-punitive unit checking
- Hints unlock after a genuine attempt
- Boss problems are available when enabled and the day’s unlock requirement is met
Guided problems students can watch
Guided problems anchor the course: interactive simulations where projectiles arc, Atwood machines turn, and carts collide — with a live data panel and scaffolded questions before, during, and after the motion.
- Guided problems across AP Physics 1, AP Physics 2, and AP Physics C
- Predictions connect the model to what students observe
- Equations, worked values, and hints help students continue
- Counts toward the daily goal (+4 points)
Algebra Blocks: symbol-pushing as a game
Students rearrange physics formulas by dragging terms — with a goal checklist, an optional one-step nudge, and a step-by-step replay. Algebra Blocks supports the Math Prep unit and selected guided lessons.
- Solve-for-the-variable practice with real AP formulas
- Mistakes are reversible — tap any earlier step to rewind
- Extra support for students reviewing algebra
Printable course materials
Daily handouts, labs, and reviews for all three courses. Public student handouts can be downloaded and used under the stated CC BY-NC-SA 4.0 license.
Tests & keys, teacher-locked
Unit tests and answer keys are served only to verified teacher accounts — never public files. Students can't URL-guess their way to a key.
A dashboard that feeds your gradebook
Classes with join codes, a per-student progress matrix by unit and day, per-class point requirements, one-click CSV/Excel export, and end-of-term archiving.
Explain the physics
Use calculations, diagrams, graphs, experiments, and written reasoning. The handouts give students room to show how their ideas connect.
Account and guest options
Signed-in practice saves progress for classroom tracking. Guest progress stays in the browser; online services still process connection information. No ads or student data sales. Read the privacy details.
Built by a classroom teacher
Developed around daily teaching, with ongoing reviews of physics, diagrams, and student support. Reports from teachers and students help identify what needs attention.
Teacher accounts
2026–2027 is a pilot year. New teacher accounts use a teacher code from Alex. Existing teachers can continue using their dashboards and account-only resources.
School privacy and accessibility review is ongoing. Before enrolling students, confirm your district’s approval and complete any required agreement with us. A teacher code or payment is not district approval. Read the current school-use status.
Practice materials and guided simulations are free to use. A teacher account for classroom tracking requires a payment of at least $5 on Ko-fi; we suggest $3 per student. Ask for a teacher code in your Ko-fi message, or email Alex if your school pays by invoice. Codes are sent personally, not activated automatically by a payment. Create a teacher account or request a code.
