Education value

I have imitated otherguys since joined school. I think I effort to 

study but the result is not satisfid. I haven't known  the study

purpose until now so I couldn't interest study. when I was In

militaryservice I really wanna read book and I read a lot of variet

y books. but now I can't concentrate reading books and any

compositions. I have test tomorrow. What do I do? just waste

time. Do I have to study for examination? why?

It's not interesting to me. I know which I've gatta do that for my

future but what is value the test point. next semester I will

select that I really need subjects. today also I did noting. hehe!!

I wanna study but I hate test.
