When grading the tests of courses with a big number of students, teacher must go to the end of the page after each grade set, in order to save and conclude the correction.
It would be easier and faster if the button to confirm and save the grading where fixed on the top of the page or beside the button to 'Send' a comment, which is fixed on the right side of the screen. For a course with just a few students is easy to conclude the grading, but if the class has over more than a hundred students to be graded, and the teacher has to scroll from the top to the bottom of the page in each student, it takes a lot of time to finish the process, which would be much better if teachers could just type the grade and click the button in a visible place on the screen, without scrolling in each evaluation.
