Perplex is for students who

Struggle with the basics

If you never mastered the foundations, moving forward can be hellish.

Our refresher modules help smooth your road to mastery.

Can't bridge theory and practice

Putting what you've learned into practice is challenging

On Perplex, you'll learn by doing, so you can go from knowing what to knowing how.

Underperform in exams

Careless mistakes, time pressure and unclear working can cripple even the best students.

By systematically practicing exam-style questions, Perplex will help you get the grade you deserve.

Built by students who know the struggle
