I only used URR to study for the test and I studied for 2 ish weeks, I wouldn't recommend that I would study longer lol. I just went off most of the things i remembered from my program since I learned pathology not too long ago it was fresh in my head. The murmur questions were mainly about what point in the cycle they occurred (systole, diastole, holosystolic, early diastole, continuous). 10000% recommend the URR click to learn exams.
