MthSc 107 Differential and Integral Calculus (2nd semester of year-long calculus) |
Spring 2012 |
The following guidelines are intended to supplement the guidelines provided on the test keys. The general guidelines address common errors which may occur in any free response question. Specific guidelines for individual free response questions are provided on the keys.
- Subtract 1/2 point for minor arithmetic or calculation errors.
- Subtract 1/2 point for not using units when units are appropriate.
- Subtract 1/2 to 1 point for minor notational errors/omissions.
- Subtract 1 to 2 points for minor algebra errors.
- Subtract 1 to 2 points where misuse of notation or operators results in a falsehood even though intentions were correct.
- Subtract 3 points or more (up to half the available points) for egregrious errors.
For example: (x + y)^{2} = x^{2} + y^{2} and √(x2 + y2) = x + y.
- Subtract 1/2 to 2 points for lapses of good taste. For example: not including "=" when clarity demands it, not indicating final answer, not reducing ridiculously simple fractions such as 2/4, not evaluating trigonometric functions of special angles such as cos (∏/4), using "=" inappropriately such as x^{2} = 4 = x = ±2, providing irrelevant information, or general sloppiness and disorganization making for overly difficult grading.
