Some students do not feel like doing a coursework revision. You have to acknowledge that sometimes you feel lazy to do the coursework revision. And you pass your coursework to your teacher setting hopes upon the fortune.
 
If you are an accurate and diligent student, you may expect a high grade, because your work may need no revision. However, if you are an average student, it is more likely that your coursework requires at least some slight revision, and its quality will be very poor if you do not do the coursework revision.
 
Everyone can make a mistake. You are certain to have started to work on your coursework several days (or even several weeks) ago. Do you know what it means? It means that you could have forgotten to point something, or might have pointed the same data twice, on after another. If you did the coursework revision, you could easily correct this error. But you refused to do the coursework revision, and that is why your grade is much lower than it could be.
 
Sometimes, students get the lower grades because of their laziness and irresponsibility. For example, some mistakes could have been made by chance. You did not take a notice of it first. But if you would have done the coursework revision, you could have corrected it, and your grade could have been much higher.
 
Dear students! Do not be lazy to do the coursework revision if you care about your grades. If you revise your paper, you can improve its quality and get an excellent grade. It is not difficult at all, especially if you revise your coursework a day or even two days after completing it. You will have to devote an hour or two hours to the coursework revision, but the results you will attain then will be much better.
