Quiz Grade Substitution Process

If you lose points on an in-class Quiz, you can earn back some of the lost points through a process called substitution:

• Each in-class Quiz will have two questions.  All questions on all Quizzes will be worth the same amount.

• Every question on an in-class quiz, Qx, will have a matching question on the final, Fy, called the paired question, with the pair being (Qx, Fy).  In most cases these questions will be identifiably similar, such as both concerning the writing of User Stories.  In a few cases they may be dissimilar questions, because a similar question was not asked on the final exam.

• For the two quiz questions for which you have the most to gain through substitution, you will get full points back for the paired question.  That is, for (Qx1, Fy1) and (Qx2, Fy2) such that:

  • (%Fy1 - %Qx1) >= all other pair differences, and

  • (%Fy2 - %Qx2) >= all other pair differences, except for (Qx1, Fy1),

 on a percentage basis, %Qx1 and %Qx2, will be substituted with %Fy1 and %Fy2, respectively.  This, for example, allows you to get full credit for a Quiz that you missed.

• For the remaining questions, you can get half the lost points back.  That is, if you do better on a paired question Fy on a percentage basis, i.e., %Fy > %Qx, the substituted grade for Qx (on a percentage basis) will be  (%Qx + %Fy)/2.

• There will be no exceptions to this policy.

Note that these substitutions will be calculated automatically, e.g., through a spreadsheet calculation, so there is nothing that you need to do or ask for.
