Thanks to everyone who helped me with the letter grading and ranking formula for columns 17/Q and 18/R above. I wish to trouble you all again
with two requests. After incorporating the two solutions above and entering my summer class grades, it was so sweet that I would like two other
things automated.

First is the cumulative grade column 15/O.
Presently, I add the available grades divided by the available total. When I grade each additional assignment, I add that to the total in this
column's formula manually which gives me the cumulative. Is there a way to automatically do this or am I expecting too much? I have removed
grades in column K, L, M so I can show the difference in calculation between column O and P. Assuming there are 10 assessments for the class in
the semester and 7 have been graded. Column O shows the grade for each student as 100% of the total grade. Column P shows the appropriate
fraction of the total grade for the assessments as a fraction of the overall knowing that there are 3 more assignments ungraded. Column O gives
me a better snapshot of each students performance at any point in time.
The second problem is numbering the students in column 2/B.
I want to manage the number for each student so that it does not matter when I add or remove a student in the roster. Right now students are
registering for the fall classes and I add their names according to their alphabetized last names. I have to re-sequence this column constantly.
I appreciate all the help that anyone can throw at these problems.
