PrepTra
Crack the CSS exam code with 25 years of past-paper analysis.
Overview
Instead of reading paper after paper without direction, PrepTra shows historical patterns across compulsory and optional CSS subjects, then lets students drill AI MCQs at their current level on a phone.
What we built
PrepTra is an Android CSS exam prep app. It turns papers from 2000–2025 into recurring topics, repeated questions and theme patterns, then builds Easy / Medium / Hard MCQ practice with instant feedback — so students practise what examiners actually ask.
