It's unsurprising that a teacher-student ratio around 1:1 could yield incredible academic results. If that so often comes at the cost of skills necessary to operate in the vast majority of real world environments though, it's kind of useless.
I don't disagree that schools are completely artificial environments. However what matters is that they're able to teach skills that are necessary in most real-world environments.
In a leadership role, being exasperated by half the team? Not motivating.
Also, the premise is that you are ahead of the bunch. It's also feasible that you are below the local average, and have no experience dealing with that situation. Takes guts to persist in that situation, but that's where you learn a lot.
