Is there anyone who still hasn't started studying

Only 20 days left for boards and I don't know why im so chill. I was stressed throughout the year but right after January started I'm extremely chill, going out, watching series, shopping, picnic and couldn't care less about exams. I know this might be unusual. I feel like if i get 75% its enough and i haven't been studying at all. I have always been a topper who would obsess over getting 90%+. What happened to me suddenly

Anyone else like me?
