Grade Spreadsheet - The Concepts

• Once we create the spreadsheet, we don’t want to have to change it – other than adding the grades we receive

• It should be accurate in terms of the output

• It has to exclude areas where a grade has not been given yet

• It must have provisions for areas that can have multiple parts, e.g., class grades or exercises.

Average/Grade Specifications• Cell A1 should contain your name• The main work area must show component names, e.g., exam1,

points possible, points received, overall average and letter grade

• Calculations and procedural areas should not be visible in the main area (Columns A-M, Rows 1-35)

• It must work correctly and provide: the average as a percent with one decimal place and the grade as a capital letter

• It should allow for multiple values (inputs for points and possible points) for class grades and exercises
