I just tried multiple times to get an answer here but i was not successful. Trying to study for OAT is simple for people who are familiar with subjects like Chem,Physics etc,but what about a foreign graduated MD who does not have any clue regarding the above subjects and wants to continue his or her carrier in Opto! Which books should he or she buy to start preparing for the OAT? Could books like Kaplan OAT help a person who is not familiar with subjects like Chem or Physics or its better to study other books which are more basic and starts subjects from the early begining or if there is any other material which can help? Please if anyone was or is in a situation like me answer this question.
