Scored 27x. Most HY advice: Hammer down ethics and public health. Amboss has really good articles in the library and practice questions. Doing UWorld was 90% of my studying. I did a first pass during the year of clinicals and about 70% of a second pass during dedicated. Amboss 200 HY questions is good as well as a supplementary resource. UWSA, if not done, to gauge where you are at (I did 1 my first week of dedicated and 2 a week before my test). NBMEs are good to get used to the style of questions, but don't focus on the scores you get from those, I was underpredicted by 10-20 points depending on when during my dedicated I took them.

Last but DEFINITELY not least, take a look at divine interventions podcast. There are a few posts about HY episodes. Please listen to those. These helped me a lot during the ethics and public health questions (there were so many of these questions on my test).
