Six-hour training or Six hours' training

Which option is correct, or both are are both?

Six-hour training
Six hours' training

So, here it is my idea:

In the first case, the hyphened six-hour training works as a compound adjective and therefore the noun hour does not take the plural inflection, whereas in the second example hours is pluralized because it is not a compound form and it takes the genitive 's as any plural noun does.

Any idea/correction would be much appreciated!

 Just use 6 hour training

Can anyone help me with the correction correct this text?

Maths exam

In these days i live a tension I am worried, why? I am studying in the University and this week I have final exams and I am so nervous . I am so scary scared with maths,. I understand all the entire class and the excercises, but when I try to do a problem I can´t!
I study Business so I think that I wanna want to be good in maths so the next year I will study and practice more, I need it ! My teacher in this class is good but she talks fast and I think, 'God you are can you hurry up or what?' I hate it .. Is That's not all,. The class is from 7:00am until 9:00am and she finishes at 8:30,. I think she has to go to the University to do the another class just for win to earn some money..
Monday is my math examen so I have to study so much a lot, but my cellphone me distracts me so I say to my mom, 'please don´t take me my cellphone until monday and close turn off the internet..' ..
I hope have a good exam in on monday !!
