I am about to finish my sophomore year at an academically competetive private college in Pennsylvania. Here are the (related) courses I have taken thus far: 2 Semesters General Chemistry 2 Semesters Organic Chemistry 1 Semester General Biology 1 Semester Cellular/Molecular Biology 2 Semesters Physics Is it too early to take my OAT this summer? Again, it'll be the summer after my second year of undergrad. I feel as though this is the best time as I will have just finished organic chemistry and physics. The OAT is good for two years, correct? So when I apply my senior year, it will still be valid? Thanks in advance!
