I study so hard and yet my dad is not satisfy?

i study so so so hard. I get A for every single subject. But i can only manage to get 100% for English and Maths. But even for other subjects, d lowest would be 96% or 98%. i always get first in my cl and yet my dad is not satisfy. He is always saying I'm stupid and stuff. He expects me to get 100% for each subject. It's stressing me out. I hate people calling me stupid wheres i'm actually more smarter than many people. What am i suppose to do?
