^they're on point describing the programs. As for competitiveness for acceptance, you've got to have a ridiculously competitive application. Along the lines of 3.8-4.0 GPA in a science heavy major, an MCAT that is +90th percentile, you're own presentations and publications in research projects (so working several years/100's of hours of undergrad in a lab), strong letters of rec from professors, MD's, AND PhD's, plus all the usual stuff that makes a stellar medical applicant. So you've gotta fit shadowing, clinical experience, volunteering, leadership, etc in there. Surgery can be done with MD/PhD, but you usually need a PhD that's aligned with your surgical field (not sure how much neurosurgery research there is out there). I work with an MD/PhD Transplant surgeon who both runs a lab in transplant immunology and does quite a bit of surgery, but he doesn't sleep more than a couple hours a night and rarely sees his kids and wife.
