Jason, Trini, Kimberly, Zack, Billy and Tommy were sitting and chatting in the cafe in the gym Tommy: "I think today's exam will be easy"

Zack: "I think it won't be easy"

Kimberly: "Of course it won't be easy if you haven't prepared for the exam" Trini: "This will be easy."

Billy:"Kimberly is right, the exam will not be easy unless you study."
