Ngàn Lá is the study hub I wish we had in high school. It collects exams for grades 10–12 across every subject, textbook, and curriculum, so students can go from discovery to practice without jumping between PDFs and social groups.
The focus is simple: find fast, practice smart, review deep. Students can browse by textbook or topic, take exams online, save the papers they care about, and then replay their full session to see exactly how they moved through each question.
