Generally speaking, yes (and that’s after a quarter century of working with college freshmen, although there’s plenty of research to back up my observations). However, you must realize that in any large population, there’s a huge range of individual performance. Yes, most students continue to perform in college they way they did in high school, BUT I’ve seen students admitted on probation wind up on the dean’s list first semester and more commonly (sadly) really good students crash and burn.
