ManaDrill is an online question-drill platform for certification and exam prep. It manages over 10,000 questions by field and automatically extracts weak points from each learner's results.
The experience of "reviewing only your weak points, extracting just the scope you need and keeping a learning record" — in 7 months we built it in-house from scratch: a new-platform launch story.
The company behind ManaDrill provides an online question-drill service for certification and exam prep. It systematically manages questions across a wide range of fields — math, English, IT and more — using per-field hierarchical categories.
Beyond just 'solving questions,' it tailors what's asked to each person's weak points, aiming to maximize learning efficiency.
The key wasn't a generic quiz app, but how to design an experience that directly drives learning efficiency.
We needed a system that automatically extracts the questions you got wrong and serves them first.
A large question bank had to be flexibly filtered by hierarchical category + keyword — that design was essential.
We needed to accumulate answer history and accuracy for each user and visualize it.
A foundation letting operators manage questions, categories & notifications themselves was essential.
Together with Amela, we built the core learning cycle — 'extract → answer → record → review weak points' — in-house from scratch. By structuring question, category and answer data, we created a system that gets more accurate the more you solve.
