HOW ADAPTIVE WORKS
Practice that responds.
Correct answers build mastery. Misses go into your review queue. In Adaptive mode, question difficulty adjusts based on your recent performance.
All questions in this demo are original, written for skill practice—not copied or reconstructed from secured exams.
OFFICIAL PRACTICE, WHEN YOU WANT IT
Use the real sources directly.
These open the official providers’ own practice tools. STEM//COMMAND does not copy, scrape, or store their questions.
MOCK LAB
Practice the pressure.
Build a mock
RESEARCH LAUNCHER
Find the official scope first.
Enter a custom competition, then open a web search for its official rules, challenge descriptions, and legitimate prep materials. The app does not scrape or reuse unauthorized questions.
For Caltech EWB and World STEM League, mocks draw from the relevant original STEM practice pool.
STUDY ARCHITECT
Your route, built around your life.
Design or recalibrate
THE PROMISE
Useful, not punishing.
Architect can build for SAT, ACT, Caltech EWB 2026, or World STEM League. It uses your event date, time budget, confidence, performance history, and rest days. Regenerate whenever life changes—the plan rebalances without shaming you for missed days.
SCORE / READINESS LAB
See the direction—not a guarantee.
Trajectory
These are unofficial estimates generated from in-app practice results, not a promise or an official score conversion. Official SAT and ACT scores can vary due to many factors.
TEST INTELLIGENCE
Study the patterns, not rumors.
Skill-family priority forecast
Estimated relevance based on your history and publicly available scope or blueprints—not knowledge of any future test or competition round.
Source standard
STEM//COMMAND uses original questions and may direct you to official, publicly available, or properly licensed practice resources. It does not use leaked, stolen, unreleased, paywalled, or unauthorized exam content.
What this means
A high priority means “practice this skill family first,” never “this exact question will appear.” The goal is durable readiness, not false certainty.
STUDY SQUAD
Friends, challenges, and friendly competition.
Share your progress
Send your readiness update or a friendly challenge through Messages, AirDrop, email, or any app your device supports. Nothing is uploaded by STEM//COMMAND.
This prototype keeps squad data on your device. Real-time shared accounts and chat would need a future online service.

FRIENDLY CHALLENGE BOARD
Cheer each other on.
ABOUT STEM//COMMAND
A calmer, more personal way to prepare.
BUILT BY STUDENTS, FOR STUDENTS.
Why this was made
STEM//COMMAND was built around a simple belief: students deserve serious tools that fit real student life. It brings practice, feedback, planning, and progress into one adaptable system—so the next step is clear, even when the goal feels big.
The experience is designed to make test preparation feel more organized and less overwhelming. It supports confidence through preparation; it is not medical or mental-health care, and score projections are estimates, not guarantees.
Start free. Upgrade only if it helps.
Free includes usable practice, one active event, progress tracking, basic planning, explanations, and personalized study support.
Core · $24.99 once unlocks the full command center: unlimited goals and events, advanced planning, expanded mock and forecast tools, and deeper progress tools. There is no required monthly membership.
Extensions, individual packs, and bundles
An extension is one focused area, such as SAT, ACT, PSAT, a specific AP course, a competition, or College Applications. It unlocks tools for that subject only.
A bundle groups related extensions together for a better one-time value—for example, SAT + ACT, AP subject groups, or the complete AP bundle. The Marketplace shows which tools each item includes before purchase.
Your verified purchases belong to your signed-in account and appear in Pack Tools after Stripe confirms payment.
How personalization works
Practice results, timing, confidence signals, preferred plan style, available time, event date, and accessibility choices shape the next recommendations. Missed skills go into review; correct answers build mastery; a diagnostic or practice result can create a new personalized plan.
Question explanations tell you why an answer is right or wrong, and you can ask for an explanation of every answer choice.

What saves where
Your signed-in purchases and College Application Pack workspace are stored securely online with your account.
For now, study history and Earn It progress are saved in the browser where you use the app. They remain after a refresh on that device, but will not automatically appear on a different phone or computer yet. Clearing browser/app data can remove them.
Friends and messages are designed for student collaboration; only share progress you are comfortable sharing.
GOOD TO KNOW
Built around honest prep.
STEM//COMMAND uses original practice questions and points students to official sources where appropriate. It does not claim to know future exam questions, guarantee scores, or use leaked or unauthorized content.
