How it works
Learn it. Practice it. Launch it.
Every session runs on the same short loop, and every step pays off.
01
Learn in clear steps
Seven steps per lesson: warm up, try, learn, work examples, practice, spot a mistake, and check what stuck.
02
Every right answer pays
Earn Funding and a fuel cell. New, harder, and due questions pay the most, so the best money move is the best learning move.
03
Launch, upgrade, go higher
Six cells fill the tank. Launch, spend Funding on better parts, and push past the clouds toward space.
The Rocket Program
Every right answer builds a rocket.
Answers earn Funding and fuel. Fill the tank, launch, and spend what you earn on engines, tanks, and guidance. Your skills set the ceiling: mastering tiles on the Board unlocks better parts.
Full practice tests earn Flight Certifications

Desmos mastery
The calculator is on the test. We teach you to win with it.
The online ACT puts a Desmos graphing calculator on screen for every question. Every lesson shows the Desmos way beside the algebra: the exact keystrokes, what to click, and when algebra is faster.
- Solve a system by clicking where two graphs cross
- Test answer choices in seconds, not minutes
- Timed Desmos drills in Launch Prep and review
Click where the lines cross. The point is your answer: x = 3, y = 4.
The method
Built on how learning actually sticks.
Every feature traces back to research on memory, math learning, and attention.

Retrieval, not rereading
Quick questions after every idea. Pulling an answer from memory beats reading it again.
