\label{Spreadsheet_About} The \textbf{Spreadsheet} is used to tell LON-CAPA how to determine how many points a student gets for the LON-CAPA portion of the course. Spreadsheets are extremely flexible and powerful and can draw upon nearly all aspects of the data LON-CAPA stores about a student. Spreadsheets can be simple things that simply give one point per completed problem to a student, or powerful things that give bonus points for completing problems early or penalties for late completion,, completing problems on the first try, differing values to different problems or problem parts, or just about anything else you could desire.
