Do people drop out usually because of failing classes?
Failing to get any internships/thinking their chances at getting a residency is low? Failing to pass boards? Maybe the timeline in my head is incorrect and these would have happened later?
What's with the preoccupation with failure? Most med schools try to salvage people who fail, but it depends upon how much they fail.
For example, at one school I worked at:
Fail one class- remediate exam. If you fail, you repeat the year.
Fail two classes- dismissal
At my school,
Fail one class- remediate exam. If you fail, you repeat the year.
Fail two classes: remediate,but then you have to sign a contract that you can't fail any more exams in the future.
Fail three classes, depending upon how badly you fail, and the explanations (ie, health issues? Distracted by life evens, or poor time mgt or motivation?) you are either dismissed, or told to take an LOA and fix the broken parts, and/or go and heal.
If you failed Boards 2x at my school, you're done. Other schools let you have 3+ chances.

Preclinical years are the first two years of med school. That's when the risk of failing out is highest. In years two and four, student take Board exams. Failing these is not good, but not necessarily lethal if one passes ont he retake. But never passing Boards means you don't graduate.
Not getting a residency is an employment thing, like you not getting a job. You still have the medical degree, but you don't get to practice Medicine.
Failing out students is the business model of the Carib schools.
Getting back to your OP, students who attend the newest schools tend ot be the weakest ones, because those schools have trouble attracting the talented students, and so they're desperate to fill seats.
That said, med school is what you make of it. You're not more likely to fail just because you're at a new school...that's on you.
