Conversion Policy Note
Percentage-to-letter and percentage-to-GPA scales vary across secondary and postsecondary institutions. This converter and chart reflect GPAPath's standard reference scale (a typical 10-point bracket with plus/minus increments). Always verify the grading policy in your course syllabus or institutional registrar handbook for exact cutoffs.
Frequently Asked Questions
Grading scales vary significantly by institution. In most standard college and high school systems using plus/minus modifiers, 80-82% is assigned a B- (2.7 grade points). In simple 10-point scale systems without minuses, 80-89% is a flat B (3.0 grade points). In weighted high school AP/IB classes, an 80% can earn up to 3.7 or 4.0 weighted grade points. Always verify your school district or university registrar rubric.
A C+ typically represents scores in the 77% to 79% range. It indicates satisfactory academic mastery above the minimum passing benchmark. While 2.3 is standard across most U.S. institutions, some universities use 2.333 or omit plus/minus modifiers entirely.
Most secondary and post-secondary institutions map 70-72% to a C- (1.7 grade points). In schools without plus/minus grading, 70-79% constitutes the full C bracket (2.0 grade points). Always verify with your institution’s official handbook.
Standard U.S. grading typically caps grade points at 4.0 for both A and A+ so that students cannot exceed a 4.0 unweighted GPA. However, select colleges (and law school LSAC calculations) credit an A+ as 4.33 quality points.
The standard U.S. breakdown is: 90-100% = A, 80-89% = B, 70-79% = C, 60-69% = D, below 60% = F. While some curved college STEM courses may assign a C to lower raw percentages, the common reference scale treats 60% as a D.
A 75% percentage mark corresponds to a C grade (2.0 quality points) on standard U.S. 10-point grading scales. A 3.0 represents a solid B average.
Under the standard 10-point plus/minus system: 93-96% is an A (4.0), 97-100% is an A+ (4.0), and 90-92% is an A- (3.7). However, individual instructors and syllabi can establish custom cutoffs (for example, requiring 94% for a full A).
