What is the AMCAS GPA?
The AMCAS (American Medical College Application Service) GPA is a standardized grade point average used by most allopathic (M.D.) medical schools in the United States to compare applicants from different colleges and grading systems. AMCAS calculates two primary GPAs from your transcript: a cumulative (overall) GPA and a BCPM GPA. The BCPM GPA, often called the “science GPA,” specifically includes all Biology, Chemistry, Physics, and Math courses you have taken. This standardization is critical because it allows admissions committees to have a consistent metric for evaluating academic performance, regardless of whether a student’s school uses a plus/minus system, inflates grades, or has other unique policies.
Unlike some university calculations, AMCAS includes all course attempts in its calculation. If you retook a class, both the original failing grade and the new passing grade are factored into your AMCAS GPA. This provides a complete and transparent academic history. Therefore, it’s essential for any pre-med student to understand how to calculate GPA using AMCAS rules to accurately gauge their standing. You can learn more about application strategies by reviewing the medical school application timeline.
The AMCAS GPA Formula and Explanation
The core formula to calculate a GPA is straightforward: the total quality points divided by the total credit hours. However, the key to an accurate AMCAS GPA calculation lies in using the correct quality point conversions for each letter grade. AMCAS uses a specific scale that may differ from your home institution’s. The formula is:
GPA = (Sum of [Credit Hours for Course × AMCAS Grade Point]) / (Total Credit Hours)
This same formula is applied twice: once for all your courses to get the Overall GPA, and a second time using only BCPM-classified courses to get the BCPM GPA.
AMCAS Grade Conversion Chart
Here is the official conversion scale used by AMCAS to convert letter grades into grade points on a 4.0 scale. It’s crucial to use these specific values.
| Letter Grade | AMCAS Grade Point |
|---|---|
| A / A+ | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D- | 0.7 |
| F | 0.0 |
Practical Examples
Example 1: Mixed Course Load
A student takes the following courses in a semester:
- Biology 101: 4 credit hours, Grade A- (BCPM)
- Calculus I: 4 credit hours, Grade B (BCPM)
- English Literature: 3 credit hours, Grade A
- Psychology 101: 3 credit hours, Grade B+
BCPM Calculation:
Biology: 4 hours * 3.7 points = 14.8
Calculus: 4 hours * 3.0 points = 12.0
Total BCPM Points: 26.8 | Total BCPM Hours: 8
BCPM GPA: 26.8 / 8 = 3.35
Overall Calculation:
Total Points: (14.8 + 12.0) + (3 hours * 4.0) + (3 hours * 3.3) = 26.8 + 12.0 + 9.9 = 48.7
Total Hours: 8 + 3 + 3 = 14
Overall GPA: 48.7 / 14 = 3.48
Example 2: A Science-Heavy Semester
A student focused on pre-med requirements takes:
- Organic Chemistry II: 3 credit hours, Grade B+ (BCPM)
- Organic Chemistry Lab: 1 credit hour, Grade A (BCPM)
- Physics I: 4 credit hours, Grade B- (BCPM)
- Biochemistry: 3 credit hours, Grade A- (BCPM)
In this case, since all courses are BCPM, the BCPM GPA and the semester GPA will be the same.
Calculation:
O-Chem II: 3 hours * 3.3 points = 9.9
O-Chem Lab: 1 hour * 4.0 points = 4.0
Physics I: 4 hours * 2.7 points = 10.8
Biochem: 3 hours * 3.7 points = 11.1
Total Points: 9.9 + 4.0 + 10.8 + 11.1 = 35.8
Total Hours: 3 + 1 + 4 + 3 = 11
Overall & BCPM GPA: 35.8 / 11 = 3.25
Understanding these details is as important as achieving high MCAT scores for a competitive application.
How to Use This AMCAS GPA Calculator
Our tool is designed to simplify the process to calculate GPA using AMCAS standards. Follow these steps for an accurate result:
- Add Courses: For each class on your transcript, click the “Add Another Course” button to create a new row.
- Enter Credit Hours: In each row, enter the number of credit hours for the course. This can be a whole number (like 3) or a decimal (like 1.5 for a lab).
- Select Grade: Use the dropdown menu to select the letter grade you received. The calculator automatically uses the correct AMCAS point value.
- Mark BCPM Courses: Check the “BCPM?” box if the course is in Biology, Chemistry, Physics, or Math. This is crucial for an accurate BCPM GPA calculator function.
- Calculate: Once all courses are entered, click the “Calculate GPA” button.
- Interpret Results: The calculator will display your primary Overall GPA, as well as your BCPM GPA, total credits, and total quality points. A bar chart will also visualize the comparison between your overall and science GPA.
Key Factors That Affect Your AMCAS GPA
Several factors can influence your GPA calculation, and it’s important to be aware of them:
- Plus/Minus Grades: AMCAS counts them. A B+ (3.3) is significantly better than a B (3.0), and an A- (3.7) is different from an A (4.0). Our calculator correctly weights these.
- Repeated Courses: Unlike some universities that replace grades, AMCAS averages them. Both the initial and repeated attempts are included in the GPA calculation.
- Study Abroad Grades: If your study abroad program was through a U.S. or Canadian institution, those grades are typically included. You must ensure they are on an official transcript.
- BCPM Classification: Correctly identifying your BCPM courses is vital. Misclassifying a course can alter your science GPA. As a rule of thumb, if 60% or more of the course content is in one of the BCPM disciplines, it should be classified as such. A strong science GPA calculator depends on this accuracy.
- Withdrawals: A simple withdrawal (W) doesn’t affect your GPA. However, a withdrawal while failing (WF) is treated as an F (0.0 points) and will negatively impact your GPA.
- Pass/Fail Courses: Standard pass/fail grades do not get factored into your AMCAS GPA calculation, though the credits may be counted as “supplemental hours”.
Frequently Asked Questions (FAQ)
1. Why is my AMCAS GPA different from my school’s GPA?
Your AMCAS GPA will likely differ because AMCAS uses its own standardized grade conversion scale, includes all repeated courses, and may classify courses differently than your home institution.
2. How do I classify an interdisciplinary course for BCPM?
You must classify a course based on its primary content. If a “Biomedical Engineering” course was taught by the engineering department but was over 60% biology and chemistry content, you should classify it as BCPM. AMCAS reserves the right to re-classify if they disagree.
3. Are community college courses included in the AMCAS GPA?
Yes, all undergraduate coursework from any accredited U.S. or Canadian institution, including community colleges, must be reported and will be included in your AMCAS GPA.
4. What about graduate-level courses?
Graduate courses are calculated into a separate Graduate GPA. They are not combined with your undergraduate GPA. Our tool is designed to calculate your undergraduate GPA.
5. Does an A+ give me more than 4.0 points?
No. For the purposes of the AMCAS calculation, both an A and an A+ are weighted as 4.0 grade points.
6. What happens if I don’t enter a grade for a repeated course I failed?
You are required to enter all attempts. If you omit a grade, AMCAS will find it during the verification process and return your application to you for correction, which can cause significant delays.
7. How are labs graded?
Labs are treated as separate courses. If your one-credit chemistry lab earned you an ‘A’, you would enter it as a one-credit course with a grade of ‘A’. This can be a great way to boost your BCPM GPA.
8. Where can I find the official AMCAS grade conversion rules?
The AAMC (Association of American Medical Colleges) publishes an official AMCAS Applicant Guide and a Grade Conversion Guide with the full details, which we used to build this calculator.
