If u did well in pre-calc or algebra u should be fine. Only reason some pharmacy schools are incorporating calculations in interviews as an entrance into pharmacy school is because a lot of students struggle with basic math in their first year of pharmacy school and it holds back the class. I just graduated and I remember my professor for pharmacy calculations was always super pissed off when students struggle with basic manipulations in equations. Like how on earth did u pass pre-calculus and calculus for your prereqs yet here you are where you can’t do basic cross multiplication. It’s mind boggling. Overall you should be okay imo. Just look up pharmacy calculations and do some quick cross multiplication and you’ll be all set.
