Please go over the key and make sure you understand the answers. My rough guidelines to grade ranges are indicated on the graph. Subjective opinions on score ranges:
< 50: you will need to improve to pass the course.
50-60: You are missing most of what you shoould be getting out of the course.
60-70: Significant gaps in understanding.
70+ : In good shape.
Please let me know if there is anything I can do to improve your comprehension of the material.
Precise grade cutoffs will be determined only based on final results for the course.
