Congrats on that MCAT!!
My two concerns (take them with a grain of salt as I'm a lowly applicant as well) are:
1.) no hook/uniqueness
2.) is the publication a primary authorship or more of a chance-based thing from the lab you joined
Of course, the top schools are always a crapshoot so if you write well, I'd imagine you'll have some success.
Overall: I'm confident that you will have choices of where to attend, but I am unsure if Columbia will be included in those choices.
Then that solves both of my questions in a sense! I have no doubt you can articulate yourself well in secondaries and interviews with that track record so I think you’re in good shape for the T10!I’ll keep those in mind. Thanks! And I was one of the primary authors for the publication
