Taking for Letter Grade

Taking Pass/Fail

GPA unchanged (P/F not counted)
How This Is Calculated
Symbols:
current_GPA = your current cumulative GPA
current_hours = total credits attempted so far
grade_points = GPA points for your expected grade (A+ = 4.0, A = 4.0, A− = 3.7, etc.)
course_hours = credits in this course
Example:
You have a 3.50 GPA from 45 completed credits. You take a 3-credit course and expect an A (4.0 points). If you take it for a letter grade:
new_GPA = (3.50 × 45 + 4.0 × 3) ÷ (45 + 3) = (157.5 + 12) ÷ 48 = 169.5 ÷ 48 = 3.53
If you take it pass/fail instead, your GPA remains 3.50 (P/F grades do not count toward GPA at most institutions).
Grade Point Scale
Most US institutions use this standard 4.0 scale:
| Letter Grade | Grade Points | Percentage (typical) |
|---|---|---|
| A+ | 4.0 | 97–100 |
| A | 4.0 | 93–96 |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C− | 1.7 | 70–72 |
| D+ | 1.3 | 67–69 |
| D | 1.0 | 63–66 |
| F | 0.0 | Below 60 |
Note: Some schools use different scales (e.g., A+ = 4.3, or no A−) and some count A+ separately. Always check your school's official grading scale.
Frequently Asked Questions
Does taking a course pass/fail affect my GPA?
At most colleges, a Pass or Fail grade does not count toward your cumulative GPA at all. Your GPA remains unchanged whether you pass or fail the course — no grade points are added or subtracted. However, the credit hours may still count toward your degree progress and full-time status. Check your school's registrar to confirm, as a small number of institutions do count a failing grade into GPA even under pass/fail options.
Can I convert a pass/fail grade back to a letter grade later?
This depends entirely on your school's policy. Some colleges allow you to convert a P grade back to a letter grade within a set window (e.g., the next semester), while others do not allow conversion at all. Once graded as pass/fail, you typically cannot change it retroactively unless your registrar offers a formal petition process. Clarify this with your academic advisor before enrolling pass/fail, especially in a course that might be relevant to graduate school or job applications.
Do employers or grad schools see pass/fail grades differently?
Employers rarely scrutinize the format of your transcript and generally focus on your overall GPA and relevant experience. Graduate schools and professional programs (law, medicine, etc.) do see pass/fail courses on your transcript and may view them differently depending on the program and field. STEM graduate programs, for instance, sometimes prefer to see letter grades in prerequisite courses. It is safest to assume that professional and graduate programs may weigh or question pass/fail courses more heavily than letter grades, especially in major or prerequisite courses. Contact the programs you are interested in to ask their specific expectations.
Which courses can I take pass/fail?
Most schools restrict pass/fail grading to electives and do not allow it for major requirements, prerequisites, or core courses. Many also cap the number of credits you can take pass/fail per semester or per degree. Check your course catalog and degree audit to see which courses are pass/fail eligible, and verify whether a course you want to take pass/fail counts toward your major or degree requirements.
Should I take this course for a letter grade or pass/fail?
This tool shows you the arithmetic, but the decision depends on your goals. If you need to raise your GPA, a strong letter grade will help. If you're confident you'll pass but worried about a low grade, pass/fail protects your GPA — but it also means no GPA boost if you excel. For courses relevant to graduate or professional school, a letter grade is usually safer. For electives in a subject you're unsure about, pass/fail can reduce stress. Talk to your academic advisor about your specific situation.
My school uses a different grading scale. How do I adjust?
This tool uses the standard 4.0 scale used by most US colleges. Some schools use a 4.3 scale (A+ = 4.3), use different letter boundaries (e.g., A is 90–100 instead of 93–96), or do not assign A+. Look up your school's official grade point scale on your registrar's website and adjust the grade points in this calculator accordingly. The formula remains the same; only the numbers change.
