Programs:

• Program does not run: -80%

• Program runs with some errors: -20%

• Code is difficult to understand: -10%
  Include comments in your code wherever needed!

• Program runs but misses the point of the exercise: -20%
  For example, a for command is used instead of recursion.

• Program runs but is not useable for its intended purpose: -60%
  For example, print is used instead of output in a helper procedure or a predicate produces no output.
• Program not useable for its intended purpose but programmer has demonstrated proficiency: -20%
  For example, print is used instead of output but assignment objectives are otherwise met and the program runs for grading purposes.

• Program exceeds requirements: +5%
  For example, program responds well to invalid input.

Short answer questions:

• Answer indicates insight beyond the scope of the question: +5%
  For example, detecting and discussing a way around a flaw in a command.

• Answer completely correct and clearly written using complete sentences: full credit

• Answer correct but not clearly written: -10% to -30%
  E.g. "It gives the remainder when dividing the one number by the other. If the one number is a positive the thing will be positive otherwise it has to be negative."

• Partially correct answer: -20% to -70%
  E.g. not explaining how the remainder command handles negative numbers.

• Partially incorrect answer: -30% to -80%
  E.g. claiming that the output of remainder is always positive.
