The seniors have college exams.

I was absent for most of my senior year.

Delinquent seniors, I think they're Sunohara and Okazaki.

Yeah, the seniors especially are busy with entrance exams.

As a senior, you should be more aware of your actions.

Third-years focus on studying for entrance exams, so they don't get much homework, right?

I thought I'd heard of Yagami Light somewhere, so I looked him up. It seems he was the Junior High Champion in 2002 and 2003.

He was tall, so maybe he's a senior.
