SDN Members don't see this ad. (About Ads) I am finishing up my sophomore year of undergraduate college and still have to take Organic chemistry 1 and 2 as well as physics 1 and 2. I heard that physics 2 is not really tested on the OAT exam. However, I do not know if it is a good idea to take orgo 1 in the summer and then take orgo 2 during the fall semester of my junior year. Then I would take physics 1 during the spring semester of my junior year. Need advice since I am not sure which classes to take since those are the only pre requisites I have left for optometry. Also, I want to do well in the OAT yet am afraid that taking these big sciences will take away time studying for the OAT exam.
