Método QRV is a professional police exam preparation app that helps students study in a structured and consistent way, always knowing what to study next. It uses the QRV method (Questions, Reviews, Video Lessons) combined with personalized study plans, daily guidance, integrated practice questions, videos, PDFs, mentoring follow-ups, and progress tracking. The app was built entirely in Nowa in less than 2 weeks by Ewerton, whose background is military firefighting with no coding or Flutter experience. He built the app for his company, Mega Simulados, a Brazilian exam-prep company focused on competitive public exams.
