petso turns prep for high-stakes exams into a daily habit: real practice questions, a plan that adapts to you, and a pet that levels up when you do.
How it works
Fifteen minutes a day. The plan decides what you see.
Step 1
Exam-style questions with a written explanation on every one — including why each wrong option is wrong. Nothing on exam day is a format you have not already seen.
Step 2
Every question you answer comes back just before you would forget it, scheduled by FSRS — the same spaced-repetition scheduler Anki uses. It runs fully offline and syncs when you are back.
Step 3
Your pet grows every time you study. Showing up is the only part left to you — the plan decides the rest.
Get a question wrong and petso walks you toward the fix — you still do the finding. On every question, free, even offline.
petso Plus adds a real back-and-forth conversation about the exact question in front of you. It guides your reasoning — it never just hands you the answer.
Retrieval
Answering a question builds memory faster than rereading the explanation. It is why every session asks before it tells, and why the explanation only appears after you have committed to an answer.
Spacing
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 instead of when you happen to feel like it.
Two minutes, ten questions, one AI opponent that sometimes beats you. A quick way to test yourself under a clock.
You compete only against people sitting your same exam session — and a bad week never follows you.
A lesson tree for your exam, a ten-minute daily quest and a weekly challenge. XP feeds your pet, so academic wins are emotional wins.
Your pet grows when you study. It never dies, never shames you, and one missed evening does not undo a month — pick it up tomorrow and nothing is lost.
Scheduled by FSRS — the same spaced-repetition scheduler Anki uses.
