Science GPA calculator
This science GPA calculator separates your coursework into Science (Biology, Chemistry, Physics, Math) and Non-Science sections and computes three GPAs at once: your BCPM science GPA, your non-science GPA, and your combined overall GPA. Medical school applicants use the BCPM GPA when submitting AMCAS applications.

What Is a Science GPA Calculator?
A science GPA calculator computes the BCPM GPA - Biology, Chemistry, Physics, and Math - used in medical school admissions by calculating the credit-weighted average of grades earned specifically in these four subject areas.
- Calculates BCPM GPA from Biology, Chemistry, Physics, and Math courses only
- Used for medical school AMCAS applications and pre-health advising
- Separate from the overall GPA - medical schools review both figures
- Requires identifying which completed courses fall into the BCPM category
- A strong science GPA demonstrates lab and quantitative course performance
Medical school applicants submit two GPA figures through AMCAS: the overall cumulative GPA and the science (BCPM) GPA. The science GPA captures performance specifically in the quantitative and laboratory courses most predictive of success in medical school curriculum. Because pre-med students often take heavy science loads, the BCPM GPA can differ significantly - higher or lower - from the overall GPA.
How to Calculate a Science (BCPM) GPA for Medical School?
Identify all BCPM courses
List every completed Biology, Chemistry (including Organic and Biochemistry), Physics, and Mathematics course from all undergraduate terms.
Exclude non-BCPM courses
Do not include Psychology, Sociology, English, or other non-BCPM courses in the science GPA calculation.
Apply the standard 4.0 scale to each grade
A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, D=1.0, F=0.0.
Multiply grade points by credit hours
Compute quality points for each BCPM course: grade points × credit hours.
Divide total quality points by total BCPM credits
Science GPA = total BCPM quality points ÷ total BCPM credit hours.
Worked Example
BCPM courses: Bio A (4cr, 16pts), Chem B+ (4cr, 13.2pts), Physics B (4cr, 12pts), Calc A- (4cr, 14.8pts). Science GPA = 56.0 ÷ 16 = 3.50.
Science GPA Benchmarks for Medical School Admissions
| Medical School Tier | Average Science GPA (Matriculants) | Notes |
|---|---|---|
| Top 10 MD programs | 3.8–3.95 | Highly competitive; overall GPA also ≥ 3.8 |
| AAMC average (all MD programs) | ~3.65–3.72 | 2023 AAMC data for accepted applicants |
| DO (osteopathic) programs | ~3.4–3.6 | Lower than MD median; MCAT score also weighted |
| Caribbean / international MD | ~3.0–3.4 | Competitive varies widely by program |
| Advisory minimum target | 3.5 BCPM | Below 3.5 science GPA warrants pre-health advising review |
Science GPA calculator - Specialized GPA Systems
While the standard 4.0 scale is universal in the US, certain institutions and programs use specialized GPA calculations. Understanding these variations is critical for law school (LSAC), University of California system, or medical school (AMCAS) applicants.
LSAC GPA (Law School)
The Law School Admission Council (LSAC) calculates its own GPA for law school applicants. This LSAC GPA often differs from the school-reported GPA for several reasons:
- LSAC counts all undergraduate coursework, including transfer credits the school may have excluded
- Courses taken at multiple institutions are all included
- LSAC uses its own grade conversion table, which may differ from the school's
- Repeated courses: LSAC counts both the original and repeated grade, not just the better one
Full details on LSAC GPA methodology are available at lsac.org.
UC System GPA
The University of California system recalculates GPA from 10th and 11th grade a-g courses:
- Only a-g courses count (English, Math, Lab Science, Foreign Language, History, Elective, Visual/Performing Arts)
- Extra weight for up to 8 semesters of UC-approved Honors/AP/IB courses (+1.0 bonus per grade)
- 9th and 12th grade courses are not included in the UC GPA calculation
- Maximum honors points capped to prevent inflation

Specialized GPA Requirements by Program
| Purpose | Minimum GPA | Notes |
|---|---|---|
| Law School (LSAC GPA) | 3.5+ | Median LSAC GPA for admitted students at top-14 law schools is 3.7–3.9. LSAC includes all undergraduate courses. |
| Medical School (AMCAS) | 3.5+ | AMCAS calculates overall GPA and a separate science GPA (BCPM: Biology, Chemistry, Physics, Math). |
| UC System Admission | 3.0 (weighted) | UC calculates a capped and uncapped weighted GPA from 10th–11th grade a-g courses only. |
| Science GPA (pre-med) | 3.5+ | Medical schools evaluate science GPA separately. A low science GPA below 3.2 significantly reduces admission chances. |
| GPA Without Credit Hours | Varies | When courses have no credit value, use 1 credit per course for an equal-weight average. This calculator supports no-credit calculations. |
| GPA from Percentage Score | Varies | Convert percentage to letter grade first, then to grade points. 90%+ = A = 4.0, 80–89% = B = 3.0, etc. |
Common Mistakes With Specialized GPA Calculations
Assuming LSAC GPA equals the school-reported GPA
Problem: LSAC includes all undergraduate courses (repeated courses both counted, all institutions combined). The LSAC GPA is often lower than the school-reported GPA.
Fix: Calculate LSAC GPA early in the application process by entering all undergraduate coursework from all institutions, including repeated courses with both grades.
Not calculating science GPA separately for medical school
Problem: Medical school applicants who only track overall GPA miss the BCPM (Biology, Chemistry, Physics, Math) science GPA, which is evaluated independently by AMCAS.
Fix: Enter only BCPM-classified courses into a separate calculator session to compute science GPA. Track it alongside overall GPA from sophomore year onward.
Including 9th or 12th grade courses in UC GPA calculation
Problem: The UC system uses only 10th and 11th grade a-g courses. Including 9th or 12th grade courses produces an incorrect UC GPA.
Fix: List only 10th and 11th grade a-g courses when calculating UC GPA. Apply the UC honors cap (maximum 8 semesters of bonus points).
Calculating GPA from percentage without using the correct conversion scale
Problem: Different institutions define letter grade cutoffs differently (some use 90% for A, others use 93%). Using the wrong conversion produces an inaccurate GPA.
Fix: Use the school's published grading scale for conversion. Most US schools: A = 90–100% or 93–100% depending on the policy. Apply the specific cutoffs from the institution's catalog.
