Hi Heather: I'm afraid you have misunderstood how the purpose of "edit requests." The requested edits process is used by editors with a conflict-of-interest to propose specific changes and have impartial editors review the change before it is implemented in the article. Thus, such proposed edits are required to be specific and attributed to reliable sources. However, edit requests are not meant for "please do research and update the article", because if it were, the edit request backlog would rapidly become unmanageable. Washburn University does publish its grade distributions for each class, perhaps you could crunch the numbers and calculate an overall GPA curve? Good luck with your project.
