Class is soo boring all i can think about is sleepy whats a good way to past the time

Sometimes when a class gets boring, i'll ask a teacher questions that i find more interesting about the topic. 
you can ask how the material is applicable in real life, or if they know some shortcuts or tricks for tests on the subject.

Getting sent to detention, lol
i'm just kidding, just stare at the clock until 3: 00pm
