that entirely depends on you shiki. it's either you start a great topic for us to have a good conversation or you just end up randomly picking a topic just to ebb our boredom~
anyway~ like i've said. it will be up to you to make it interesting. to keep the boredom away at school you could always strike up a conversation to someone. if you're the shy type, just bring something that you can do to occupy your mind like game console or a book if that suits you. but if you're in a class and you find it real boring, just doodle some stuff on your notes or you could simply think up of a scenario(i always do this with BL in mind).
but if you still think that it is a moot point to be there. you should rethink about studying.
mhh there are so many overrated things in human society like Money having a good job it has to be always the best of the best
and yet life could be so mutch simpler
