I Need Help

I Have near perfect test scores but i study for 5-7 Hours each day and i feel like im reaching my breaking point. Our geography teacher is kinda weird and doesn't tell us what we have to study so we have to study the entire chapter each time we have geography and it ends up being really exhausting. Tomorrow we're writing a test on geography and I've been sitting staring at the material for 2 hours but just can't learn it even though it's only a singular chapter. I got in a really nad arguement with my mom since i wanted to give up and not study anymore since i had a headache and my ears hurt from the yelling. She yelled at me to study and that it will be an embarrassment for me to go and get bellow a 19 (out of 20) since my GPA will be ruined. What should i do
