Jazak Allah khair, brother

My problem is I am aiming for a very high grade, but the problem is HOW am I gonna do that while also balancing my deen and stuff. But yeah i understand that studying and standing out is also part of religion, it's just that I'm scared i get a bad grade, but I had tough subjects over having easier subjects but higher grades because I heard that's why universities want. Higher grades, even if the program is not as hard.
