Is my righting natural and appropriate?

Today has been a good day. I had played a game all day with my friends. The game we were playing was Mario Kart 8 and I always beat them but things weren't all sunshine and rainbows I procrastinated all the homework and had to hand them in tomorrow. I think bunking off would be the best solution. Worse yet, I had't revised anything yet. The school exam is around the corner. My grade is going to doomed. Should I cram? Most pros said cramming is not the best method so I think it's time to face the exam. Cramming doesn't help me pass the exam anyway.
