PRO TV, 2026
I presented Geografie BAC, the web platform and app students use to prepare for the Romanian geography baccalaureate. They practise directly on maps, exactly like in the exam, work through quizzes, simulate the full paper with automatic grading, and compete against each other in real time. Progress syncs between web and mobile, and all of it is free. Around 1,100 students used it ahead of the 2026 exam, just weeks after launch.
