Guided practice · Mistake repair
Think first. The answer unlocks after you do.
Every problem comes with a hint ladder instead of an answer key. Every miss comes back with a name and a fix, not a red X.
Hints before answers
Four rungs, from a small nudge to the full solution. You climb only as far as you need, so the thinking stays yours.
Misses get a name
Not just “wrong.” Stemry names the pattern “missing inner derivative” so it becomes fixable.
Repairs win the points back
Each repaired pattern feeds topic mastery and unlocks the next challenge. Mistakes aren’t dead ends here.
Product preview
Start with what you already have.
Your notes, problem sets, and review sheets are enough. When early access opens, your first upload becomes a topic map, guided practice, and a clear next step.
Built first for college math, beginning with calculus.
Early testers may be invited to help shape Stemry.
