The Story
Invictus isn't a single-teacher pilot — it's a whole-school deployment. Dr Brian Li, Head of Science, brought SudoStudy to the school in late 2025 and within months it had spread across 10 teachers and 7 subjects. That kind of organic adoption speed is exceptionally rare in edtech.
True department-wide adoption
Most school edtech deployments stall at 1–2 teachers. Invictus has 10 teachers actively building and assigning quizzes across Chemistry, Physics, Biology, Business, Economics, Maths, and ICT. This is a shared department tool, not a personal productivity hack.
Subject Coverage — 305 Quizzes Across 7 Subjects

Students use it independently
14 students have created 5+ of their own quizzes for revision — not teacher-assigned. This is the rare edtech tool that students don't have to be pushed to use.
