school sucks and i'm tired

So tomorrow i'll have a school exam
and i dunno i'm just really tired.
These past weeks have been really tiring and to be honest i don't really know why.
I'm guessing it's my poor sleep schedule or smt but i'm not just phisically tired, i'm mentally tired too.
Exams and school in general are draining all my energy 'cause i spend 9 hours a day there. And i wish i could at least skip one day or two just to have a little time for doing stuff i actually like,
but my dad doesn't really like the idea of me skipping school and i have to go to school literally every day. EVERY. DAY.
And i'm not kidding. I have at least 3 or 4 absences THIS ENTIRE YEAR!!
Now, i know it's my obligation to go to school and my dad is not wrong at all for not letting me skip one day but aw man i dunno, i just want to stay in my bed untill 12PM and finish my sonic adventure playtrough
Am i asking for too much? lol
At least i have my friends to keep me company and make school suck a little less
