Please go over the key on reserve and make sure you understand the answers. My rough guidelines to grade ranges are indicated on the graph. My subjective opinions on score ranges:
< 45: you will need to improve to pass the course.
45-70: Significant gaps in understanding, decreasing gradient of confusion.
70+ : Good understanding, differences in degree rather than in kind in going from 70 to 98.
