PTCAS GPA Calculator
Quick answer: PTCAS recalculates every applicant’s GPA from their transcripts on a 4.0 scale: A+ and A are both 4.0, A- is 3.7, B+ 3.3, and F, E and WF are 0. Every attempt of a repeated course counts, pass/fail and AP credit are left out, and quarter hours are multiplied by 0.667. Each course is placed by its PTCAS course subject, which decides whether it counts in the Science, Science and Math GPAs.

How PTCAS calculates your GPA
PTCAS: “…each A-F or 0-100 grade you entered in the Grade field is first converted to a PTCAS numeric grade value, then multiplied by the attempted credits. The resulting product is Quality Points. Your total Quality Points are then divided by your Attempted Credits to determine your GPA.”
“PTCAS calculates all GPAs in semester hours. Courses that were completed in quarter hours are converted to semester hours. The conversion ratio is 1.0 quarter hour = 0.667 semester hours.” “PTCAS does not recognize an individual school's policies for forgiveness, academic renewal, or grade replacement for repeated courses. PTCAS will verify based on how grades for repeated courses are reported on the official transcripts. All grades earned for repeated courses are factored into your PTCAS School GPA.”
“Non-graded credits are not included in your GPAs. Non-graded credits are earned credits for which you did not receive actual letter grades (e.g., advanced placement credits, "pass" or "satisfactory" credits, college board AP exams, courses taken as pass/fail, etc.).” And “…a grade of WF (i.e., equivalent of a withdrawn with penalty, withdrawn failing, etc.) is factored into GPA calculations as an F.”
Which GPAs PTCAS reports
PTCAS lists Science as a category of its own (with its own subject list) and defines Science and Math as the combination of its Science and Mathematics categories. Many subjects sit in more than one PTCAS category — Anatomy, for example — and count in each of them, exactly as PTCAS’s table lists them.
Type the course subject that matches the course on your transcript — the box suggests PTCAS’s own subject names. A subject PTCAS does not list still counts in your overall GPA.
PTCAS grade values
Letter grades on your transcript take these values (PTCAS grade value chart):
| Grade | PTCAS value |
|---|---|
| A+ | 4.0 |
| A | 4.0 |
| A- | 3.7 |
| AB | 3.5 |
| B+ | 3.3 |

Worked example
PTCAS applies one formula to every GPA. Five courses — an A in a 4-credit course, a B in 3 credits, a C in 4 credits, a D in 3 credits and an F in 3 credits — give 16 + 9 + 8 + 3 + 0 = 36 quality points over 17 attempted credits: 36 ÷ 17 = 2.12. (This is the worked example in PharmCAS’s help center; the arithmetic is the same in every Liaison service.)
