Helping students prepare
smarter for O Levels
Gradex was born from a simple observation: students need better tools to prepare for exams. Not more distractions — better practice, clearer explanations, and real feedback on their progress.
Our Story
We started Gradex because we saw how hard it is for students to find quality practice materials. Revision books are expensive and often outdated. Online resources are scattered and unreliable. And most study apps are designed for other countries' curricula.
We wanted to build something different: a focused, reliable practice app specifically for Zimbabwean O Level students. An app that works offline, uses minimal data, and actually helps you understand your weak areas before the exam.
Today, Gradex offers multiple quiz modes, level-based progression, and weekly performance reports — all designed to help you prepare smarter. We're constantly adding more content and improving based on student feedback.
