To accurately describe errors you should (1) show work for any questions that requires calculation (multiple choice or short response), and (2) explain not only the correct answer which is in red on multiple-choice questions but also why all others possibilities are incorrect, and(3) redo the entire short-response problem part (such as 29A, 29B, or 29D rather than all of 25) that you received less than full credit, and (4) complete parts of the question that you skipped (27A, 27B, or 27C) .

Since question 7 was dropped due to an error by Professor Gold, one extra credit point is awarded for correctly determining the answer to just this one question. That single questions will not be included in the above points.
