Letter Grade Reference
B− GPA — above the floor,
below every threshold.
A B− earns 2.7 quality points — safely above academic probation but below the 3.0 floor that graduate programs, most merit scholarships, and employer GPA cutoffs require. It's the grade that passes without opening doors. Use the calculator to see exactly where you stand.

The buffer grade
2.7 GPA — safe
but not sufficient
A B− occupies an uncomfortable space in the GPA landscape: it's clearly passing, meaningfully above academic probation, and feels like a reasonable outcome. But in terms of what it unlocks, 2.7 falls below every commonly cited threshold for post-undergraduate opportunities.
Graduate program minimums are almost universally set at 3.0. Scholarship renewal requirements start at 3.0. Employer GPA cutoffs in competitive recruiting are typically 3.0 or 3.2. A student whose cumulative GPA is 2.7 — built predominantly on B− grades — is above the floor of academic standing but below the floor of most meaningful opportunities.
The practical implication: a student earning B− in all courses is academically secure but optionally constrained. Improving to B (3.0) each semester requires approximately 0.3 additional GPA points per course — a meaningful but realistic target. Use the calculator to model how many strong grades it takes to reach 3.0.
Path to 3.0
Moving from B−
to a 3.0 GPA
Recovering from a B− average to reach 3.0 requires consistently earning B or better. The math depends on your current credit total. If you have a 2.7 GPA over 60 credits (162 quality points), you need enough B grades to pull the average to 3.0. That requires approximately 27 additional B credits — roughly two semesters of all-B performance.
A more efficient path: aim for B+ and A− grades in new courses while maintaining B in others. Mixed-grade recovery is typically faster than all-B recovery, and it builds the kind of transcript that shows improvement — which graduate programs and employers notice.
One frequently overlooked lever: grade forgiveness or course replacement policies. If B− grades appear in courses that can be retaken, a higher grade on retake can replace the B− in some institutional GPA calculations. Check your registrar's repeat/forgiveness policy before retaking any course.
Common questions
B− GPA — FAQ
What is a B− in GPA?
2.7 quality points per credit on the 4.0 scale; 2.67 on the 4.33 scale. Approximately 80–82% performance — the lowest tier of the B range.
Is B− a passing grade?
Yes — 2.7 points well exceeds the 2.0 academic standing threshold. However, specific courses may require 'C or better' or 'B or better' for major credit or prerequisite clearance.
Does B− satisfy graduate school requirements?
A 2.7 average falls below the 3.0 minimum for most graduate programs. B− in prerequisite courses may signal insufficient preparation to admissions committees.
What percentage is a B−?
Typically 80–82% at most US institutions, between C+ (77–79%) and B (83–86%).
Does B− affect scholarship renewal?
A B− average (2.7) falls below most merit scholarship renewal thresholds of 3.0+. A semester heavy with B− grades can push a borderline cumulative GPA below the renewal floor.
What is the difference between B and B−?
B earns 3.0 pts; B− earns 2.7. A 0.3-point gap per course — 0.9 QP per 3-credit course. The cumulative difference over a full degree program (120 credits) between all-B and all-B− is exactly 0.30 GPA points.
How does B− affect cumulative GPA?
A 3-credit B− adds 8.1 QP. Adding B− to a 3.0/60-credit record: (180 + 8.1)/63 = 2.986. Use the calculator for your exact numbers.
How many strong grades to recover from B− to 3.0?
Starting at 2.7/60 credits, you need approximately 27 additional B-grade credits (9 courses) to reach 3.0. Mixing in B+ and A− credits gets there faster. The calculator above models this precisely.
Does B− trigger academic probation?
No — probation is triggered by cumulative GPA below 2.0 at most institutions. A 2.7 B− average is 0.7 points above that floor.
