Guys, 40% it's not his grade as in 40/100. That's the percentage where he ranks between all the other students in the mock exam. It's like it was counted from the bottom but with percentages (stupid, I know). Like, imagine there are 100 students in the mock exam. Manabu is in 60th-61st place. Let's remember he's in a super competitive cram school at the moment. He is smart and puts a lot of effot in his studies, but the competence to get in Tokyo U. is fucking fierce.
