No idea. I could be totally wrong but, to be blunt, I don't think Starfleet Academy will go the full four years with one group of cadets all going from freshman to senior. I'd be surprised.
I think Star Trek in general messed up the chance it had to gain Zoomers. So, I think this won't get them as much of the youth audience as they were hoping for.
I can tell you that when I was in school, the last thing I wanted to do when I got home was watch about characters in school. Star Trek, among several other shows and movies, was my escape from that. I'm sure a lot of young people in the would-be audience would feel the same way. They want to get away from the lives they're stuck in, not be reminded of them. Especially a sci-fi or fantasy fan. What drew me to Star Trek over 30 years ago was that it was an escape. So much worse back then. Today, I can always just leave a job and get another one. I couldn't just leave my school and go to another one. Now, I can live where I want, I can go out when I want, I can live how I want. None of that happens when you're a kid, so escapism becomes even more important at that age.
