I have taken All of the Chem courses (including Biochem) but have not taken Ochem 2. Should I enroll in a class before applying so that I can state on the application that I have enrolled in a course? Or is it unnecessary for many schools for acceptance. I don't want to put time and money into the class if it is unnecessary. If a school does require it and I have not taken it, they can still grant me admission based on completion of the course as well correct? Thanks!
