How hard can school get!?

I know cheating is not the best idea when it comes to school. Ademic intergrity is very hard for most students. I take short cuts all the time whenever it comes to schoolwork. Whwn I have alot of work to do and so little time its hard to adjust and make arrangements to get your himework done. So I might cheat here or copy my friends answers here  just to get by. I hear teachers say the only thing your cheating on is yourself and so far that does not seem to be true. In a matter of fact Im doning quite well. I know its not something I should be doing down the road but its hard not to. Everyone has there ways of getting by certian areas of their life. What I need to know is why does the world put so much pressure on education? Why can we not learn without being graded?
