Difference between a A and C paper

What makes a good paper? what i think makes a paper good is when its written about something interesting and teaches you something u didn't know. The differences between a A and C paper would be a purpose for the paper , secondly would be clarity , third would being able to relate to the paper these qualities i think are what would be the differences between a good paper from a average paper. All these qualities would make the paper easy and enjoyable to read.

the paper in its self needs to have a purpose for it and why. the paper needs to be able to give the reader a since of why this paper is being written with out that the paper wouldn't make any since and would sound like gibberish and would throw off the reader. 

The paper has to be clear of grammar, punctuality mistakes and have good sentence structure. if this was a problem in the paper it would probably just frustrate the reader and just make the paper sound dumb and make the writer look like an idiot.   

The ability to have the paper relate to other people by like describing something everyone probably gone through in their lives, for example the first i learned to ride a bike and how i scraped my knee. this is what i think makes a great paper by being to relate to stuff in the paper and being to reflect on it.

The easiest one for me would probably be writing something that everyone can relate too and describe the scene to people in the paper. I find it the easiest because its something that usually comes form the heart and i can vividly describe it clearly to people.The most difficult part of it is the ability to write in a clear with out mistake paper, grammer for me is a pain i usually have to write a paper a few times before its free of mistakes.
