Tufts uses a plus/minus 4.0 scale. An A+ is recorded but counts the same as an A (4.00).

The Math

How Tufts GPA Is Calculated

Tufts multiplies each grade point by course credits to get quality points, then divides total quality points by total graded credits.

Tufts GPA Formula
\[ \text{GPA} = \frac{\displaystyle\sum \text{Quality Points}}{\displaystyle\sum \text{Graded Credits}} = \frac{\displaystyle\sum (\text{Grade Point} \times \text{Credits})}{\displaystyle\sum \text{Credits}} \]
Quality PointsGrade point value × credits for each course
Graded CreditsTotal letter-graded credits (excludes P, CR/NC, Audit)

📝 Worked Example

A sample calculation using three Tufts courses:

CourseCreditsGradeGrade PointQuality Points
ENG 14.0A4.004 × 4.00 = 16.00
MATH 324.0B−2.674 × 2.67 = 10.68
CHEM 13.0C+2.333 × 2.33 = 6.99
Total11.033.67

Plugging into the formula:

\[ \text{GPA} = \frac{33.67}{11.0} \approx \mathbf{3.06} \]

Tufts GPA to Percentage Converter

Convert your 4.0-scale Tufts GPA to an equivalent percentage instantly.

Convert GPA → Percentage

Enter any Tufts GPA between 0.0 and 4.0.

The Conversion Formula

Tufts uses a 4.0 scale, so:

\[ \text{Percentage} = \text{GPA} \times 25 \quad \text{or equivalently} \quad \text{Percentage} = \left(\frac{\text{GPA}}{4.0}\right) \times 100 \]

Example: If your GPA is 3.5, then Percentage = 3.5 × 25 = 87.50%.

📌 Grades Excluded from GPA

The following marks carry no grade points and do not affect your GPA: P (Pass, D− or better), CR / NC (Credit / No Credit), S / U (Satisfactory / Unsatisfactory), I (Incomplete), COM (Complete), Y (Year-long course).

Under the Pass/Fail option, a grade of P is awarded for work at the D− level or better and does not change your GPA. Audited courses also appear on the transcript but are excluded from GPA.

Tufts GPA — Frequently Asked Questions

What GPA scale does Tufts University use?

Tufts uses a plus/minus 4.0 grade-point scale: A = 4.00, A− = 3.67, B+ = 3.33, B = 3.00, B− = 2.67, C+ = 2.33, C = 2.00, C− = 1.67, D+ = 1.33, D = 1.00, D− = 0.67, and F = 0.00. Your GPA is total quality points divided by total graded credits.

Is A+ worth more than 4.0 at Tufts?

No — an A+ appears on your transcript but carries the same value as an A (4.00). It's a symbolic distinction and cannot push your GPA above 4.00.

Does an F count in my Tufts GPA?

Yes — a grade of F is worth 0.00 and is included in your grade point average. No credit is earned for a failed course.

How do I convert my Tufts GPA to a percentage?

Use Percentage = GPA × 25 (equivalent to (GPA ÷ 4.0) × 100). For example, a GPA of 3.5 converts to 87.5%.

Do Pass/Fail and audited courses affect my Tufts GPA?

No. Courses graded P (Pass), CR/NC, or Audit do not contribute to GPA. Only letter-graded courses carrying grade points are counted.
