-There are three different types of spreadsheets inside LON-CAPA: Assessment Spreadsheets, Student Spreadsheet, and Course Spreadsheet. 
+There are three nested levels of spreadsheets inside LON-CAPA: a Course Spreadsheet, \index{course level spreadsheet} a Student Spreadsheet, and various Assessment Spreadsheets. The Course spreadsheet provides an overview of student performance and links to each student's details.
+The Student Spreadsheet configures how the overall course grade is to be calculated. Each graded item can
+be configured using an Assessment Spreadsheet to specify how the problem parameters are to be evaluated.

-\item \textbf{The Assessment Spreadsheets}
 
-An assessment-level spreadsheet provides access to all of the parameters
-associated with a student's performance on a particular homework assignment, quiz, 
-or exam.
-Each student has an assessment spreadsheet for every assessment in the course.
-The assessment spreadsheets provide data to their parent, the student level
-spreadsheet, via the assessment spreadsheet \textbf{export row} (\ref{Spreadsheet_Export_Row}). 
-Multiple assessment spreadsheets can be used in cases where the instructor configures
-grade categories.
-
-\item \textbf{The Student Spreadsheet}
-
-The student level spreadsheet summarizes the assessment spreadsheet data for the students.  
-There is only one default student level spreadsheet definition, 
-but the data varies for each student.
-The student spreadsheet is programmed to permit the instructor to assign different
-assessment spreadsheets for different grade categories or other uses.
-The data present in the student spreadsheet is imported from the 
-\textbf{export row} (\ref{Spreadsheet_Export_Row})
-of each assessment spreadsheet for all of the assessments currently in 
-the course.  
-The student spreadsheets pass summary data to the course-level spreadsheet
-via the student spreadsheet \textbf{export row} (\ref{Spreadsheet_Export_Row}).
-
-\item \textbf{The Course Spreadsheet}
-
-The course spreadsheet contains all of the summary data for the students in
-the course.
