Just a fellow med student finishing ms3. good job on the research, keep it up. Stay involved with the ortho department. That is probably the most important part of your app that you can work on as m1-m2.
The other thing is to study hard. Pre-clinical ranking doesn’t matter, but your knowledge base will when it comes to step 2 and shelf exams. And those will still be very (maybe more?) important now that step 1 will be P/F.
Overall, looks like you’ve done a good job so far. Keep your eyes open for the other specialties in case you change your mind. And don’t forget to take care of yourself, since being a decent person is important for both living… and clinical evals lol
