Grades... really?

The purpose of grades are to judge your ability to learn new things and apply them to real life.  I don't really mind the current grade system but I think it doesn't represent you as a person.  I do not think the current grading system represents your knowledge because they are just numbers and letters.  I think we should do a combination of both the current and standard grading system so you can see how many points you got out of a hundred and you can see how well you did which is very important.
