The method
Keys first. Doors next.
Mastery follows.
We measure how reliably you recall — and open the next level only when you’re truly ready.
Ability, not grades
A score that means how reliably you recall.
A lucky guess isn’t knowledge. Your ability rises only as your recall becomes dependable — terracotta quietly marks the skills still finding their feet.
Overall
Steady across vocabulary and listening; grammar still climbing.
The mechanic
Keys open doors.
Each card you genuinely master earns a key. Collect enough and the next door unlocks — progress you feel, not a percentage you chase.
The cards
Dozens of ways to practise one idea.
One calm shape — prompt on the left, your move on the right. Recognition, recall, repair, dictation: each angle deepens the same memory.
Ayer María come un sándwich.
The long view
A journey you can see.
Every key, every door, every climb rolls up into one honest measure of where you stand.
Practice that respects how you actually learn.
