How is a science GPA calculated?

The grade point average is calculated based on how you scored overall in the classes and the level of difficulty the subject is. Then they average the results to obtain a final GPA.

There's no straight answer for your question because it depends.....If you're going from undergraduate to graduate, it really depends on the college. At my college it would be the GPA for college classes categorized as: VTHT, BIOL, PSYC, CHEM, or GEOL. Other colleges vet programs may not include GEOL in the science GPA. If you're going from high school to undergrad, they're probably going to look at your chemistry, physics, biology, psych classes....pretty much any class that you took to satisfy your high school science requirements. The best thing to do is contact a counselor of the school you're trying to get into, or contact the department head of the program you're trying to get into...and ask them.
