Make a "working" copy of your college transcripts to date. Highlight all courses in biology, chemistry, physics and math. If you repeated a course to improve your grade, you'll need to find out the policy of the individual school to which you apply. You might be able to include only the higher or lower score. You might have to include scores from every time you took the class. Only rarely will a school allow you to drop the low score from your BCPM calculation.
Count the total number of instances of each grade that appear on your transcript in the highlighted classes. You will count an "A+," "A" and "A-" as three different grades.
Once you have total numbers of each BCPM grade, multiply each number by the following factors: "A+" = 4.0. "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" = 1.0. "F" = 0.0. So if you made three B's, you would multiply 3 x 3.0 for a total of 9.
Total all the calculations from each grade and the number of classes.
Divide the total grade points by the number of classes for your BCPM grade point average. Round it two places to the right of the decimal point.
