FWIW I'm a firm believer that in most cases a kid who is on the edge and could get full admit or Blinn Team is usually better off with Blinn Team. All of the kids I know that didn't make it in recent years were surprised to get full admit and ended up struggling, all of the Blinn Team kids are doing fine. It's anecdotal but my assumption is that you end up with kids who are smart but have to take those Freshman weed out classes with a few hundred people, many of which are basically retaking the class from High School, and they get hammered. Also they sometimes think they are good to go and get caught up in the social atmosphere and distractions of the Fall of Freshman year a little more easily, a Blinn kid knows they have to make grades and are in those small classes generally with profs that want them to succeed.
The hard thing is some kids look at getting in to college as the end goal and not just a mile marker on the marathon. Everything in High School for many of them is about getting in to X or Y school. Often they aren't really ready for what that can mean at a place like A&M that can be very unforgiving to a Freshman who doesn't have their head on straight from the beginning and there isn't much breathing room to adjust. You really need to know the game (which classes to take, what profs to avoid, how many hours you can handle, figuring out how to balance studying and social) very quickly or else they can drown.
It's definitely an individual thing, plenty of kids who are Blinn could easily make it as a regular admit and thrive. I just look at Blinn as being a nice buffer to help a kid adjust and increase their chances of success, the only negative is a mental one that some kids like the idea of feeling like a regular admit even though in reality it means nothing long term. The Ring and the Paper are what matters.
