A- is a letter grade commonly used in educational systems to indicate a level of performance that is above average but not quite at the highest level. It typically represents a score range of 90% to 93% in many grading scales. Students receiving an A- have demonstrated a strong understanding of the material and have met most of the course requirements effectively. In some contexts, an A- can also reflect a student's overall academic standing, influencing their GPA or class rank. This grade is often seen as a positive achievement, encouraging students to continue striving for excellence in their studies.
