Most walls in maths come from one earlier idea that never clicked. A free 10-minute scan finds yours, then builds your route to your goal.

See where they’re stuck, set a goal together, and cheer the wins. Learning data only, never their messages or passwords.
Your route4 lessons to your goalExampleThe Knowledge Scan adapts with every answer. Get a question right and that concept is marked as known, so it never appears on your route. No timer, pause anytime; most people finish in about 10 minutes and find they kept more than they expected.
Every step on your route is a fifteen-minute lesson: the idea in plain words, a worked example, then a few questions to check it landed.
A letter stands for a number nobody has told you yet. You can still count how many of them you have.
Each concept you finish returns as a two-minute review, timed for just before you would forget it. Scheduled by SM-2, the algorithm behind Anki.
Why spacing worksThree findings have held up in classrooms for decades. Most courses use one of them. We built the whole product on all three.
Learners who master each step before the next one score higher than learners who push on regardless. It is why the map is built from prerequisites rather than chapters.
The same study time spread over days is remembered far longer than one long session. It is why reviews come back to you on a schedule.
Answering a question is remembered longer than rereading the explanation. It is why every lesson asks before it moves on.
Your reviews arrive on their own, so showing up is the only part left to you. Streaks, XP and a weekly league make that visible, and a Recovery Day means one missed evening does not undo a month.
Tap whichever sounds like you. Nothing to fill in.
