The grading file is permitted only to accounts ending in .rpi.edu. It is at: http://www.rpi.edu/dept/chem-eng/Biotech-Environ/jon/grades.xls
Just clicking should bring it up, but if not you can download it. If you do not know how to download, GetSamba is recommended. The consultants at the help desk can quickly show you how to install and use it.
