Our rules JS is great for the calculation, but it might be nice to actually show that on screen
So for Rule B have something that says:
We discount (ignore) your mark for XYZ because it is your lowest grade at 52. Then we find the mean of the remaining marks for the year as follows: ( 54 + 55 + 67 + 74 + 81 ) / 5 = 66.2. That number is then rounded to produce your final grade of 66.
