Is there something wrong with my studying habits?

my friends are freaking out over exams and essays, but i’m playing it cool. i have a reduced load, and my teachers are a bit more relaxed than others. i always pass my exams, like high 60s to high 70s, but i dont study as much as my friends who get the same mark, and have the same classes, but with different teachers. they are completely freaking out. i bet they’re studying right now, while im on fluther.
