15 F. Why do people overhype the 10th board exams?

Im giving my preboard 2 rn and its downright annoying to read the same theory part again and again, theres not even much content in the text books to read. Im pretty sure we could all give Boards like tomorrow and we’d all get good marks. So why are they trying to scare us so bad as if we’re writing some JEE or NEET?
