Koyi marks your answers the way a Cambridge examiner does, point by point against the mark scheme. Then it makes sure the mark you lost today comes back as a question you get right next week.
Chemistry · Biology · Mathematics · Psychology. Built on the official 2028 syllabuses and real past papers.
The loop every top student runs by hand, done for you.
Every syllabus outcome is a button. Real past-paper questions come first; new exam-style ones are written when the bank runs out.
Not a score out of ten. Each mark-scheme point, hit or missed, with the line of your answer that earned it.
Anything short of full marks returns tomorrow as a fresh variant, then at growing intervals until it sticks.
The tutor knows the question you just did and asks before it tells. Want the straight answer? One tap.
Official Cambridge questions and mark schemes, tagged to the syllabus, with the original page for diagrams.
Guide mode, exam-answer mode, or explain it back to a “confused classmate”. It cites your own notes.
Built on FSRS. Each card comes back as a new question on the same outcome, rated from your score.
Upload a PDF, a photo of your notes or a slide deck: get summaries, key terms, flashcards, a practice set and an interactive explainer.
Write on paper like in the exam, photograph it on your phone, and it is transcribed and marked.
Exam dates and weekly hours in, a two-week plan out, weighted to your weakest subtopics. Missed days roll forward; nothing turns red.
A weekly report tells you how the week went and where to encourage. The conversations stay with your child, unless they choose to share them.
Koyi is invite-only while we work with a small group of Cambridge A Level students and their parents. Tell us who you are and we will be in touch.
