Have you ever thought why you do not get the same grades on your assignment as your neighbor? Who considers him or her to be better than you are? You seem to prepare the same paper, but your neighbor’s grades are higher than yours. What is the reason for such a crying injustice?
 
We have to disappoint you by telling that there is quite a serious reason pushing your teacher to evaluate your papers this way. And this reason is contained in your papers and is reflected in the mark schemes.
 
Mark schemes are the schemes, which describe the evaluating requirements. To put it plainly, let us say that the mark schemes point out what grade a student can get if his or her paper contains some particular number of mistakes.
 
There are a lot of different mark schemes. The mark schemes differ depending on the discipline, on the type of academic writing, and on the country. The requirements for a coursework, reflected within the mark schemes, can also differ depending on the course.
 
If you consider your teacher to be unjust, you can ask him or her to let you compare your results with the mark scheme, which was used for evaluating your paper. The teacher has no right to refuse to show you this mark scheme. Even if he or she refuses, you may go to the library and find it there; or you can find it within the online sources.
 
Consulting the mark schemes will allow you to make sure that your teacher is absolutely just in evaluating your papers and get rid of all the doubts you have.
 
But it is much better to ask your teacher to give you the mark scheme before you start writing your work, in order to know the requirements beforehand and make sure your paper corresponds to all the requirements.
