Test Recovery If you scored under 90% and would like to improve your grade follow the steps below. 89% is the highest grade allowed on recovered tests. ½ Credit is given for all questions corrected as instructed.

I. State what your mistaken question and answer were.

II. Explain the thinking error that caused you to miss the question.

III. State the correct answer.

IV. Justify your answer with a reference in the text. Show any work necessary to solve the problem.

Tutorial Extra Credit – 15 points I. Prepare questions you have for tutor – a

minimum of 1 question from each of the 3 levels.

II. Take at a minimum of 1 page of notes from tutorial session.

III. Have a signature from the tutor confirming your work with them.
