Where an institution publishes percentage bands the answer is exact and where it does not there is no answer at all. On the University of Toronto's undergraduate table a 95 per cent is an A+ at 4.0, an 85 is an A at 4.0, an 80 is an A- at 3.7 and a 79 is a B+ at 3.3. Those are Toronto's figures and they travel no further than Toronto transcripts.
The bands, in order
Toronto prints A+ at 90 to 100 per cent and 4.0, A at 85 to 89 and 4.0, A- at 80 to 84 and 3.7, B+ at 77 to 79 and 3.3, B at 73 to 76 and 3.0, B- at 70 to 72 and 2.7. A 95, an 85, an 80 and a 79 therefore land in four different letters and three different grade point values, and the gap between the 80 and the 79 is a full third of a grade point for one percentage point of work.
Why the boundary matters more than the number
On a banded scale the cost of a single percentage point is zero everywhere except at a boundary, where it is the whole step between two letters. A student at 79 and a student at 80 are one mark apart and 0.4 grade points apart on Toronto's table. That cliff is invisible on any scale that publishes only letters, and it is why students at banded institutions argue about single marks.
Where no band is published
Most American registrars publish a letter and a grade point and leave the percentage to the course. In that setting a 95 has no institution-wide grade point, and the syllabus for the individual course is the only source. Asking a registrar for a percentage equivalent will usually produce the same answer: it is the instructor's, not theirs.
Questions people ask about what gpa is a 95
What GPA is a 95 per cent?
On the University of Toronto's published bands, 95 per cent is an A+ and 4.0. At an institution that publishes no bands there is no institution-wide answer.
What is an 80 per cent worth?
On Toronto's table an 80 is an A- and 3.7, one mark above the top of the B+ band at 79, which is worth 3.3. A single mark at that boundary is worth 0.4 grade points.
Why does one mark matter so much?
Because banded scales convert a continuous percentage into a step. Inside a band a mark is worth nothing; at a boundary it is worth the whole step between two letters.
