Are grades really accurate?

Well.

I was thinking, about my D in math. I usually would have a B or an A. I understand the material, and if after every day of math, i was given a test about what we learned that day, i would get atleast 85-100%.

My grade is failing, because im lazy. I dont want to do my work, and i dont do it.

My math teacher isnt that strict, but he tells the truth.

I remember once, i didnt do my homework, so he says to me, "You had something better to do , right?" I told him.. "No, i just forgot", and he says " So, that means you had something better to do, right?" and i couldnt think. I told him i did. He asks "what was it?".. I told him " It was nothing"

That shows that my grade is only failing because 'nothing' as in saying ' doing nothing' makes me more excited, than doing math work. So, wheres the 'consipiricy' here?

Grades are a jip. They rob you. They rob you of your self-esteem, they rob you of your self-pride, and they rob you of friends. You can be smarter than hell in a subject, but have an F. becuase you dont like the subject. I think grades are inaccurate, because its just a fucking number. The only way they get kids like me to do my HW, is to threaten detentions. Yet, i still dont do my work. Why?

I told you, i'd rather do nothing, than do my work. How about you? Dont you feel somewhat the same way? I also think that college should be allowed to anyone, s'long as they have enough money to pay. SAT's, ABC's, its all the same.

This is just my rant, i dont even know if it fits under the category of Conspiricy. I just think there is a better way..
