I think it's somewhat institution dependent, too. For instance, my home institution's pediatrics rotation is known for having high standards, and it's almost impossible to get higher than pass if you haven't already had medicine.
Sounds like my home institution!
So, I liked RP's post for the state school comment, not as much the trying harder to get good grades. Didn't find much of the basic science stuff to be super-interesting so I didn't take it seriously. I learned it but we're P/F so I just aimed to clear the class average on each exam, and this usually turned out fine. Had no bearing on how I did on Step 1, but it did prevent me from being AOA. Which doesn't really matter for anything except Derm and the surgical subspecialties (and even then...).
I would have pushed myself to find some research project that interested me enough to follow through and write up for publication, I didn't do that in medschool because nothing excited me and I find academic writing to be quite mind-numbing. This would have certainly helped me get a few more interviews and I'd feel more confident in those abilities heading into residency.
Something I
did do that I'd recommend to others/wish I did more of is I started reading more for pleasure (poetry, mostly) and also writing/journaling intermittently. It's been nice to flip back through reflections and experiences in the past year, and when it came time to write my personal statement, it wasn't as much a bear as I thought it would be. My school has a number of pre-clinical and clinical med humanities electives and I took a number of them. Prior to these experiences I wasn't particularly interested in the arts or literature, but these electives set something off for me and now they're an important part of how I find balance and expression in my daily life. Naturally my limited writing output is quite medicine-related, but it still feels
different. Find a writing buddy if you feel stuck! A friend of mine challenged me to write a poem for some medical humanities contest after gifting her a book of poetry, and since finding somebody to write with it's become much easier for me. I haven't published or posted these anywhere yet, I'm not sure how I feel about that, but yeah, I encourage it. I think if you're the sort to be browsing the SDN Psychiatry boards this could really appeal to you
