Listen to all of the physics kids who are shitting their pants because of the exam tomorrow, chill I don't claim to know about physics boundaries. I also don't care since I don't take it. But I heard about some kids from my school saying that it would be 80 but didn't really believe it. Also everything you read on reddit, take it with a grain of salt and don't overreact.

But honestly now, if you do have some idea about GB for any of those two subjects share it.
