How is OptomCAS GPA calculated?

OptomCAS GPA is calculated by converting each letter grade into standardized grade points, converting quarter hours into semester hours when needed, multiplying grade points by credit hours to get quality points, and dividing total quality points by attempted credits for each GPA bucket across all institutions attended.

Does OptomCAS count repeated courses and failed classes?

Yes. OptomCAS includes both the original attempt and the repeated attempt, and failed coursework remains in GPA calculations. WF is treated the same as F at 0.00, while a regular W is excluded.

What coursework does OptomCAS exclude from GPA?

OptomCAS excludes non-graded credits such as pass/fail or credit/no-credit work when no letter grade is assigned. Regular W grades, AP, CLEP, in-progress, and incomplete coursework are also excluded until official graded credit appears.

What OptomCAS GPA is competitive for optometry school?

An OptomCAS overall GPA around 3.4 to 3.6 is often competitive for many O.D. programs, while stronger BCP and science GPAs can help offset a lower cumulative number. More selective programs may expect GPAs in the mid-to-high 3s.

About This OptomCAS GPA Calculator

This OptomCAS GPA calculator is built for optometry school applicants who need to estimate the GPA views commonly reviewed in Doctor of Optometry admissions: overall GPA, cumulative undergraduate GPA, BCP GPA, science GPA, math GPA, and prerequisite GPA. It also converts quarter-hour coursework into semester hours using the standard OptomCAS approach, combines coursework across all institutions attended, and reflects the rule that repeated courses still count.

How to Use the OptomCAS GPA Calculator

Follow these steps for an accurate OptomCAS GPA result

1Enter Every Graded Course Attempt

Add every graded course from every college or university you attended. OptomCAS includes repeated coursework and combines all institutions when it recalculates GPA from transcripts.

2Classify Courses the OptomCAS Way

Choose Biology, Chemistry, Physics, Mathematics, Other Science, or Non-Science for each course. Those categories determine your BCP GPA, science GPA, and math GPA.

3Set Units, Academic Level, and Year

Mark each course as semester or quarter credit, select undergraduate, post-bacc, or graduate level, and set the academic year. Quarter hours are converted to semester hours using the OptomCAS 0.667 factor.

4Flag Optometry Prerequisites

Use the prerequisite toggle for courses you want to treat as OD program requirements. This makes it easier to compare prerequisite GPA with your overall and science performance.

5Review BCP and Science GPA Together

Compare your overall GPA, cumulative undergraduate GPA, BCP GPA, science GPA, math GPA, and prerequisite GPA before you apply. Official verification can still differ if transcript classification changes.

OptomCAS Grade Conversion Scale

OptomCAS uses a standardized 4.0 grade scale for optometry school applications, and WF is treated the same as F at 0.00.

OptomCAS GPA Types Explained

Overall GPA

Includes all graded coursework from all institutions after credit standardization to semester hours. This is the main cumulative OptomCAS GPA most Doctor of Optometry applicants check first.

Cumulative Undergraduate GPA

Includes undergraduate and post-bacc coursework while excluding graduate work. This helps O.D. programs isolate your pre-optometry academic base.

BCP GPA

Includes Biology, Chemistry, and Physics only. This is one of the most important OptomCAS science-screening GPAs for optometry admissions, and it does not include math.

Science GPA

Includes BCP courses plus Mathematics and Other Science coursework, so it is broader than the BCP GPA.

Math GPA

Separates mathematics coursework so you can see your quantitative preparation on its own, including courses like calculus and statistics.

Prerequisite GPA

Includes only the courses you flag as optometry prerequisites, which is useful because O.D. programs can vary in required science and math coursework.

How OptomCAS Calculates GPA

1The Formula

OptomCAS GPA = Σ (Semester-Standardized Credits × Grade Points)

Σ Semester-Standardized Credits

Quarter-hour classes are first converted into semester hours, then quality points are calculated and averaged across each OptomCAS GPA bucket using the standardized semester-based method applied to all institutions attended.

2Key OptomCAS Rules

•All attempts count, including repeated courses.
•All institutions count, not just your current school.
•Quarter hours are converted into semester hours using 0.667 before GPA is computed.
•Non-graded credits are excluded, including pass/fail or credit/no-credit work without a standard letter grade.
•WF is treated as F, while a regular W is not included in GPA.
•BCP and science are different, because Mathematics counts toward science GPA but not toward BCP GPA.
•Academic year trend matters, because OptomCAS also lets programs review freshman-to-senior progression.

Course	Credits	Grade	Grade Points	Quality Points
General Biology I	4	A	4.00	16.00
Organic Chemistry I	4	B+	3.33	13.32
General Physics I	4	A-	3.67	14.68
Statistics	3	B	3.00	9.00
Total	15			53.00

Calculation

GPA = 53.00 ÷ 15 = 3.53

Total Quality Points ÷ Total Credit Hours = Cumulative GPA

Frequently Asked Questions

Common questions about calculating GPA at OptomCAS

Most O.D. programs pay close attention to the overall GPA, BCP GPA, and science GPA, while prerequisite GPA and cumulative undergraduate GPA also matter. Those views help programs judge both general academic strength and science readiness for optometry coursework.
