OptomCAS GPA Calculator

How OptomCAS calculates your GPA

OptomCAS: “…each A-F or 0-100 grade you entered in the Grade field is first converted to a OptomCAS 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.”

“OptomCAS 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.” “OptomCAS does not recognize an individual school's policies for forgiveness, academic renewal, or grade replacement for repeated courses. OptomCAS 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 OptomCAS 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 And “…a grade of WF (i.e., equivalent of a withdrawn with penalty, withdrawn failing, etc.)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 OptomCAS reports

OptomCAS defines BCP as the combination of Biochemistry, Biology/Life Sciences, Inorganic Chemistry, Organic Chemistry and Physics. Mathematics is a separate category and is not part of BCP.

Type the course subject that matches the course on your transcript — the box suggests OptomCAS’s own subject names. A subject OptomCAS does not list still counts in your overall GPA.

OptomCAS grade values

Letter grades on your transcript take these values (OptomCAS grade value chart):

Number grades: “…number grades are rounded up to the higher grade if they fall between the listed values. For example, if you enter 2.8, the round-up will equal 3 (B).”

Percentage grades on a US transcript:

OptomCAS publishes separate charts for Canadian transcripts:

Worked example

OptomCAS 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.)
