You learned it once.
Nobody helped you keep it.

School moved on the moment you understood. Consiliae spaces reviews on a connected maths map, so what you learn this month is still yours next year.

How it works

Three steps, and no page one.

Step one

Skip what you already know

The 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 15 to 25 minutes and find they kept more than they expected.

3/4 as a decimal = 0.75Solve 2x + 5 = 17

1234
Each answer changes what it asks next.
Step two

Learn one concept at a time

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.

Lesson 2 · intro to algebra

A letter stands for a number nobody has told you yet. You can still count how many of them you have.

2 lots of a plus 3 lots of a is 5 lots of a,
so 2a + 3a = 5a

Remember it months later

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.

Intervals are illustrative. The real spacing is set per concept, per learner.
The research

None of this is our clever idea.

Three findings have held up in classrooms for decades. Most courses use one of them. We built the whole product on all three.

Prerequisites
Nothing new lands on a gap.

Learners who close the step underneath first go further than learners who push on regardless. It is why the map is built from prerequisites rather than chapters.

Spacing
Gaps beat cramming.

The same half hour spread over three weeks is remembered far longer than one evening of it. It is why reviews come back to you on a schedule.

Retrieval
Being asked beats being shown.

Answering a question builds memory faster than rereading the explanation. It is why every lesson asks before it moves on.

Staying consistent

Coming back tomorrow
is the hard part.

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.
