I was studying for the NDEB exam and was struglling with the oral path section. I got the book which are multiple choice question and just went through them. before you know it I started to see how oral path question are worded and the topic started to kick in. Nice book for oral path if you have a lot of time to prep bc if you have a month for the exam then the book is too long if your prepping a year in advance then a good adjunct.
