Since my university offers many classes at the same exact time, I cannot take both Genetics and Molecular Biology before my MCAT. Which would you say is more important? Currently enrolled in Biochem 1, Genetics, Inorganic Chem for Fall 2015 semester. Biochem 2, Protein structure and function, Basic Cell Bio in Spring 2016. Want to take MCAT in May/June 2016. The only 2 classes that I won't really be able to take before my MCAT are the Basic Molecular Bio and Experimental Biochemistry, so wish I could take this one before but not looking like its possible. Any comments or input on the decision will be appreciated.
