Designed for students targeting 320+ on the UTME.

The 100-Day Challenge is an accelerated variant of the Project 320 Challenge for students with 3-4 months before their exam.

Ideal for students who are starting preparation late or want a focused, high-intensity programme.

Metro Manager is a mini-game inside Learn that turns study breaks into active learning. You build and manage a metro system — connecting stations, deploying trains, and clearing passengers before gridlock. Every 400 points, the game pauses and presents a real exam question from your chosen Learn subject. Answer correctly to earn resources and build faster. Answer wrong and see the correct answer with a full explanation. The game reads questions from the same pool you study in flashcards and quizzes, without disrupting your spaced repetition schedule.
