A 86 is a B and is one percentage point below being a B+. The cutoff for a B+ is a 87 minimum. However, teachers may sometimes give students the benefit of the doubt and round up to a B+. This is especially true if your percentage is a fraction above a 86, like a 86.5, 86.75 or 86.9. If the B is rounded up you would benefit from an additional 0.3 grade points in your GPA calculation.
