USC Grading System (GPA & Transcript Guide)

USC assigns letter grades that carry grade points, then calculates GPA by dividing total grade points by GPA-bearing units attempted. An A is worth 4.0 points and an F is worth 0.0. Your transcript records courses, units, grades, and academic actions. Check USC’s current rules for your student level and school before making decisions.

Warning: A letter grade, a percentage, and a GPA are not interchangeable. Assuming they are can lead to errors when you plan a retake, judge your academic standing, or send records to another school. I use the same first step in advising conversations: identify which USC policy applies to the student and course before interpreting the numbers.

USC grades, GPA calculation, and transcripts

USC’s undergraduate grade-point scale assigns a numerical value to each letter grade. Your GPA reflects those values and the units attached to each course. The transcript is the official record of your coursework and grades; it does not automatically show a percentage equivalent for each letter grade.

What grade points does USC assign?

A grade point is the numerical value USC assigns to a letter grade for GPA calculations. USC’s standard undergraduate scale includes plus and minus grades, so an A− and a B+ do not count the same as an A or B. The scale below gives the listed values.

These are grade points, not percentages. Do not assume that an A− equals a fixed percentage, or that USC’s scale matches another college’s scale. A course may use a percentage scale for assignments or final grades, but that depends on the instructor or course information.

How do I calculate my USC GPA?

GPA, or grade point average, is total grade points divided by the number of GPA-bearing units attempted. To find a course’s grade points, multiply its units by the grade-point value for the final letter grade. Add those results, then divide by the relevant attempted units.

Example: Suppose a student earns an A− in a four-unit course and a B in a three-unit course. The first course contributes 4 × 3.7, or 14.8 grade points. The second contributes 3 × 3.0, or 9. The total is 23.8 points over 7 units, for a GPA of 3.4.

A term GPA covers the applicable work in one term. A cumulative GPA includes the applicable work across terms. The calculation is weighted by units, so a grade in a course with more units usually has a larger effect than the same grade in a course with fewer units.

This table illustrates the basic arithmetic, not every policy exception. When checking a real GPA, use the units and grades USC counts for your record. An unofficial calculator can help you explore scenarios, but it cannot confirm how a specific course, repeat, or non-letter mark is treated.

What do Pass/No Pass and other marks mean for GPA?

A grading basis is the method used to report a course result. Pass/No Pass and other non-letter marks generally do not carry grade points in the standard GPA calculation. Before enrolling, check the course’s grading basis and USC rules, since eligibility and effects may depend on the course or student’s program.

Do not assume a Pass/No Pass course will meet a major, prerequisite, or professional program requirement. The course may appear on your transcript even if it does not change your GPA. Check with your academic advisor and the department that owns the requirement before choosing a grading option.

What information appears on a USC transcript?

A transcript is an official record of academic work. It lists courses and other academic information, including units and grades, and may show academic actions. A grade on the transcript is not itself a percentage unless the instructor or course separately provides a percentage scale.

Read the transcript alongside the applicable catalog and school rules. If something looks wrong, compare the posted course, units, and grade with your course record, then contact the relevant instructor or USC office promptly. Follow the published process and deadlines for resolving a grade or record issue.

Degree curriculum, course units, and academic requirements

Degree requirements are the rules you must meet to complete your program. They can include required courses, unit totals, prerequisites, and other conditions set by USC and your school. A course grade may affect GPA and degree progress in different ways, so check both before registration.

How do course units affect my GPA and degree progress?

Units measure the academic weight USC assigns to a course. They matter in two separate ways: units contribute to the total required for a degree, and GPA-bearing units weight each course’s effect on your average. The course’s role in your degree depends on your program’s requirements.

Before building a schedule, confirm that each course fits your plan. Check prerequisites, required units, and whether the course counts toward your major or another degree requirement. A class can earn units yet fail to satisfy a particular requirement, so do not rely on its title alone.

What should I check before choosing a grading basis or repeating a course?

A grading basis determines how a course result is recorded. A repeat is a course taken again after an earlier attempt. USC’s treatment of repeated courses can depend on current policy, student level, course eligibility, and program rules; do not assume the earlier grade disappears from the transcript or GPA.

Use this checklist before registering or retaking a course:

• Confirm your student level and school, then consult the current USC Catalogue and relevant school handbook.
• Check the course’s grading basis, prerequisites, units, and degree role.
• Review current rules for withdrawals, incompletes, repeats, and academic standing.
• Ask an advisor how the course fits your degree plan, and verify repeat treatment with the appropriate USC office.
• Compare possible grades using the GPA formula, but treat the result as an estimate until USC’s rules are applied.

A repeat may have more than one consequence: it can affect degree progress, the transcript, and GPA calculations. Confirm the current policy before relying on a grade-replacement assumption. This is especially important if you are near a program requirement or have questions about academic standing.

Academic success, grade questions, and student records

Academic success includes knowing how your grades are recorded and what steps to take when you have a concern. USC policies and school procedures govern these steps. Keep copies of course information and communications, and use the designated process rather than assuming that an informal conversation changes an official record.

What should I do if I think a grade or transcript entry is wrong?

Start by identifying the exact issue. Check the course, grade, and units shown in your record, then compare them with the information provided for the course. If the grade appears incorrect, contact the instructor and follow USC’s published process for grade questions or appeals.

A grade concern and a transcript error may need different routes. Ask the instructor or designated USC office which process applies, and pay attention to stated deadlines. Do not wait until an application or graduation review is due to report a possible problem.

How can I monitor progress without misreading my GPA?

Review your official record after grades post, and compare it with your degree requirements. If you use a personal spreadsheet or calculator, label it as an estimate and include only the units that apply to the calculation. Check the official USC record and current policy before making a decision based on a projected GPA.

I advise students to separate three questions: “What grade did I earn?”, “How does it affect my GPA?”, and “Does the course meet a degree requirement?” One answer does not automatically settle the others. An advisor or department can help interpret program rules, but the applicable catalog and Registrar guidance remain important references.

Accreditation, graduate study, and transcript use

Accreditation is a review of an institution against standards set by an accrediting body. USC is institutionally accredited by the WASC Senior College and University Commission (WSCUC). Accreditation is useful context, but it does not guarantee that every outside school will accept credits or that every program meets a profession’s licensing rules.

What does USC accreditation tell me?

WSCUC’s directory is the place to confirm USC’s current accreditation status. Institutional accreditation concerns the institution; it is not a promise about how another college will evaluate an individual course or transcript. Transfer decisions are made under the receiving institution’s rules.

Likewise, accreditation alone does not confirm that a program meets every professional licensing requirement. If you plan to enter a licensed field, check the relevant program and licensing authority’s requirements. If you plan to transfer, ask the receiving college how it reviews USC coursework.

Do graduate and professional programs use the same grading rules?

Not always. Graduate and professional students should check the current USC Catalogue and their school’s handbook for grading, GPA, repeats, academic standing, and degree rules. Program policies may differ from undergraduate rules, so do not apply an undergraduate scale or repeat policy without confirming it fits your situation.

When applying elsewhere or seeking employment, check what documents are requested. Some organizations ask for an official transcript, while others may request additional program or degree information. Request records through USC’s current Registrar process and confirm that the transcript shows the information the recipient needs.

Frequently asked questions

These brief answers cover common questions about grades, GPA, and records. For a decision involving a specific course or program, verify the current USC Catalogue, Registrar guidance, and school policies. A general answer cannot replace rules that apply to your student level or academic unit.

What is an A worth at USC?
An A is worth 4.0 grade points on the standard undergraduate scale.

What is an A− worth at USC?
An A− is worth 3.7 grade points on the standard undergraduate scale.

How does USC calculate GPA?
USC calculates GPA by dividing grade points earned by GPA-bearing units attempted.

Do course units affect GPA?
Yes. Units weight a course’s contribution. A grade in a higher-unit course generally affects the calculation more than the same grade in a lower-unit course.

Does Pass/No Pass change my GPA?
Pass/No Pass and other non-letter marks generally do not produce grade points. Check the course’s grading basis and applicable rules before enrolling.

Does a USC letter grade equal a fixed percentage?
Not by itself. A letter grade is not a percentage unless the instructor or course separately provides a percentage scale.

Does retaking a course erase the earlier grade?
Do not assume so. Repeat treatment can depend on USC policy, student level, course eligibility, and program rules. Check before retaking.

Where can I confirm USC grading rules?
Consult the current USC Catalogue, the Office of Academic Records and Registrar, and your school’s handbook or advisor.

Will another college accept my USC credits?
Not automatically. The receiving institution decides how it evaluates transfer credit under its own policies.

Does USC accreditation guarantee licensure eligibility?
No. Confirm professional licensing requirements with the relevant program and licensing authority.
