So my community college (semester system) offers 2 levels of ochem. They're both 2 parts and both have lab portions, but the only difference is the unit level and the class title. One of them is 4 semester units and is called Basic Ochem+biochem and the other one is 5 semester units and is just called ochem. Problem is, the 5 unit one conflicts with every other class i'm taking, while the 4 unit one does not. Would it be a problem if I took the 4 unit one?
