Both are correct, but they mean different things!

Say "At school" when you mean the general location (I am at school today).
Say "In school" when you mean you are physically inside the school building, or if you are currently a student. 🏫

Why is it "ON the bus" but "IN the car"? They are both vehicles!

Remember the Transport Rule! If you can stand up and walk around (bus, train, plane, boat), you use ON. If you have to bend down to get inside and can only sit (car, taxi, helicopter), you use IN. 🚌🚗
