weirdly feeling kinda confident for boards

I'm currently in the 10th grade. the board exams are approaching, but idk why I just don't seem to be scared/panicking. I don't know whether it's overconfidence because I scored above average in my second preboards, or the fact that I completed my syllabus way back in september and have revised concepts at least 5-6 times by now.

i just don't feel scared about the board exams approaching, i have been studying roughly 1-2 hours lesser than I was earlier, I just don't feel like studying a lot. is this normal? i find it weird considering I used to feel nervous before giving my class 9th final exams, but now I just feel oddly calm.
