As a Bio major, i need to take Ochem and Genetics(1st sem)/ Cell Molec( 2nd sem) next year. Is it a bad idea to be taking these science classes with Ochem because im a Bio major. Or do you guys recommend taking it at different time or just changing majors to just focus on the pre-req. I'm really considering changing majors so i can focus on the pre-req instead of overloading myself with science classes. What's the most popular sequence of classes that most pharmacy students took?
