I have briefly studied the entire Kaplan study text and I have found some topics in OT context explained in the textbook with additional information and some topics which are not included in OT context I have studied entirely from OT but.. I am worried about missing important information if I ignore the study text and follow only OT. Can you please guide me? And I would like to appreciate all the effort put into OT lectures and notes, I have passed 9 papers thanks to OT! Thank you
