@ucbalumnus, yep, schools like NMTech aren’t hard to get in to, but that’s why it has a high drop-out rate (22% 4Y graduation rate).
In any case, I’m all fine with kids sorting themselves in or out of majors if money was not a concern. For most people, however, money is a concern, and it’s tragic if a kid embarks on engineering or pre-med, sinks in large amounts of money (or takes on large loans with the expectation that they would be able to pay them off), gets bad grades, and thus can’t transfer in to a program they can handle but is close to their interests (like nursing) or ends up going to a program like CNC machining which they could have entered initially out of HS (essentially wasting money or taking on onerous loans because of a false start).
