Science GPA is for classes that count as sciences. AKA math, bio, chem, physics.
Directly from ADA website:
"Science GPA: All undergraduate, graduate, and cumulative courses identified on your transcript as Biology, Chemistry, Physics, Math and Other Science is used in computing this GPA."
"BCP GPA: All undergraduate, graduate, and cumulative courses identified on your transcript as Biology, Chemistry and Physics are used in computing this GPA."
If it has a minimum sGPA of 2.85, then in theory it should be counting classes under the sGPA definition above.
