Nerzia is the study app I wish existed when I was failing exams. Reading notes and watching lectures never worked for me—the only thing that helped was testing myself. But finding good practice questions for specific topics online was nearly impossible. So I built Nerzia. Type any topic and it generates real exam-style questions in seconds. It explains mistakes, tracks weak spots, uses spaced repetition, and even maps your knowledge visually—making studying quick, focused, and surprisingly fun.
