1 pt. for answer clarity. Was this answer clear, concise, and easy to understand?
- 1 pt. for effort. Was there an appropriate amount of thought and time put into the creation of this answer? That doesn’t necessarily mean a long answer. If a short response answers the question well, it is appropriate. If more detail is required to answer the question well, a longer answer is appropriate.
- The remainder of the points will be awarded for answer accuracy, with multipart questions reflecting a higher potential point total.
