Lab 3 Grading

Part	Points
CarpetBill	15
Correctness (10 points) 5 points for division into separate sections (declarations, input, processing, output) 5 points for correct output -1 point for each incorrectly calculated value -2 if sales tax isn't declared as a constant -2 if currency isn't printed correctly ($0.##) Style (5 points) 5 points for variable names and specifications -1 if the sales tax is declared as a constant but not named with all caps Other -8 for not turning in .mcp file -2 if CS99.jar is missing Points off at grader's discretion if .mcp file cannot be opened and project run No credit if .java file is missing
EquationSolver	15
Correctness (15 points) 5 points for declaring and using a method that calculates determinants. This must be a method that calculates any determinant given the four values in the matrix, not a specific method for solving for x or y. -2 points if they wrote a separate method for x and y, but not a method for determinants in general. No penalty for having separate methods for x and y that call a general method. 5 points for correct output 5 points for dividing into input, processing, and output sections Other -5 for not turning in .mcp file -2 if CS99.jar is missing Points off at grader's discretion if .mcp file cannot be opened and project run No credit if .java file is missing

General comments:

As you know, we were lenient this time for the many students who did not turn in their assignments to the correct FTP directory by the due date/time.

We permitted them to FTP their solutions to the proper directory DURING LAB WHILE RICK WAS OBSERVING without counting the assignments as late; Rick made sure the files being transferred came from a source that was last modified before the due date/time.

If any files were submitted to your FTP directory with a late timestamp and Rick did not explicitly observe their transfer, they are considered late.
Equation solver: If you used integer division to solve the equations, you will be unable to correctly solve any system of equations with a non-integer solution. (Try it.) This is a significant error.
