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.
To do automatically it seems quite hard, even in real spreadheet programs it require many if structures, checking if field is empty or no. Maybe you make extra copy row with "percentage weights", but make zero weights of assignments not yet done, and use new weight row for column 15? Then you put new weight in new row to make assignment active for "cumulative grade"?
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.
This I do by using field formula for first field, then column formula for rest:
address@hidden::@5$2=1
