How do I make me study?!?

My school finals are in less than 2 months. THIS decides how good of a college i get into, AND ALSO my dignity.
My school's been having these revisions from November WITHOUT a gap we started i around the last week of Nov and currently on the last subject of 7th revision!!! with one more to go.
You can ideally SEE why we are burnt out

I am losing hope, the grades have not been increasing in ANY manner, while some have gone down. I am just NOT ABLE TO STUDY. The sleep schedule, I tried waking at 3/4am to study till 6am before getting ready for school. Worked for the first couple of days then I started sleeping
Tired taking 2 sets of nap, one in the afternoon for 2-3 hours and another at night 10/11pm-11/12am
then studying through the morning, with an hour sleep from 5-6am before school. AGAIN, worked the first couple days then boom.

ATP, i made it a habit to randomly go over instagram reels or short. I dont even like them much but whenever i see my book my brain goes off
I tried conditioning myself with small rewards, NOPE
I tried to motivate myself with bigger rewards and goals, NOPE
I tried pomodoro, i js ignore the timer and do what i do
I tried different POSITIONS to sit, NOPE
I am just simply losing hope. I DO NOT want to study, but i SOOO badly want my marks because i know i am NOT someone to settle for less. (no, that doesnt motivate me)

This needs severe help :<!
