What did I say that was incorrect? Nontrads have an EC advantage because living longer gives them more ECs, work experience, volunteering, whatever. That's pretty much a fact.
Sure, assuming that you are
only referencing nontrads who knew they wanted to go into medicine and purposefully took time off.
Otherwise, you run into a lot of people who are attempting to take prereqs on the side while continuing the career they already started (fulltime job + halftime classes), who have kids, who have
both 😱 or who honestly never knew they wanted to go into medicine until later in life.
The kid who has known they want to be a doctor since freshman year of college has 4 solid years (half of each of which they have no academic obligations), can take research as a course, knows profs in the research community, probably knows of programs at the local hospitals, etc...
Deciding later means you have to balance all of this with your current life, lack the premed resources you would have in school, rarely take summers off, and are ineligible for a lot of the great experiences such as research internships, summer premed programs, etc...
Even if you only put it in terms of time, most traditional students have 3 or 4 years to look into ECs, and most nontrads are trying to find the shortest path to medicine from wherever they may be when they decide.
