What grades are good?

Good grades typically indicate a strong understanding of the course material and a high level of academic achievement. The exact definition of a good grade can vary depending on the grading system used by an individual school or university, but generally speaking, grades in the A range (90-100%) are considered excellent, while grades in the B range (80-89%) are considered very good. Grades in the C range (70-79%) are considered average or satisfactory, while grades below the C range are considered failing or unsatisfactory. Some grading systems may also use plus (+) and minus (-) signs to further differentiate between grades within each letter range.
