My scores were very similar. I studied Hansen/Roach, radoncquestions.com, and the green book and did very well.
With that said, in my opinion, in-service has slowly improved over the past 4-6 years yet there still remains some significant differences between in-service and written boards.
Looking back at old in-service tests there was a big element of useless trivia and lots of junk like random/rare GU cancer staging or minutia. I felt like it got better over the years and in-service as an exam overall improved. The ABR clinical I thought was pretty well done. A good combo of general numbers (survival, local control, or side effect % for the MAJOR practice changing/standard of care setting phase III trials), overall management principles (ie does this patient need surgery, what sequence, what radiation dose, what staging studies needed?), and anatomy/staging. Not as much trivia as inservice I felt.
Others may disagree, but that was my take.
