For those of you in pharmacy school, do you think applicants should take Ochem in the beginning of their pre req journey or wait until the last 2 semesters before admission? Is Ochem used much in Pharm school or is it mainly human biology and A&P stuff? I am just wondering if I should take A&P classes now and wait for Ochem until a little later or visa versa.
