Add mean, median, number of test takers and percentage for grades #62

One problem I encountered last semester is when I record 60 for a course and got a GPA of 0 set by original barriers. I got a 3 at the end semester which is to pass the course. In this case, my record is basically useless for the semester. I need to change everything at the end of the semester, including barriers. This usually happens, when professors promise each student should have an 83 out of 100 to get a GPA of 3 to pass the course, eventually those who get 60 can get a GPA of 3. Because most assignments are too hard to reach a high score. But many times professors give a percentage line, like 20% of students can get an A. We can do some predictions based on our scores like mean and median values. This could be helpful to not changing the whole grading barriers once and once again during the whole semester.

Here is my personal view: 1: Add the mean and median values to show the average performance of a class. Some extra information like "falling behind", "step ahead', would be beneficial for students to understand their grades better. 2: Add the number of test-takers and my rank to the grades, you can also get a percentage for your overall performance to the test. Like, get a rank of 20 out of 30 test-takers. So I get 66.67% among all test takers. Although I got 90 out of 100, I am not doing good at all. I may not get a high GPA as shown in my APP. So GPA prediction based on the percentage of total test taker and score you received would be more helpful and accurate 3: Add some distributions to curve grades in one button, most professors use the normal distribution, but t dist, chi dist, uniform, triangle dist are also useful. It would be better if I can add formulas heard from the professor, like sqrt(your score)*10 4: We can choose our barriers, like use percentage on GPA or grades on GPA, or both at the same time.
