My brother took a gap year - he had an opportunity to live abroad, work, have fun, and then dive into engineering when he came back. He also didn’t apply himself in HS (however from age 16 worked a FT factory job 3 -11 shift after attending high school from 8 - 2:30), he had a newspaper route very early, and then a job starting at age 14 (short order cook) and had a stock portfolio at age 15; smart, just applied himself in college and later career.
I see where a student ‘falls short’ first semester college, at a away college with football, fraternity, etc distractions, and maybe never having to study in HS - some parents pull the kid right then. If they bomb 2nd semester, they have pretty much scratched that college, lost their scholarships, and unless they have a number of semesters (perhaps CC or local school) and a few years to bring themselves up from the cellar in regard to GPA to ever return to that school or a similar school. I’ve seen a student get military service in after bad grades in college freshman year, and then return as a serious and focused student with fabulous grades. I have seen a very capable person (ACT 33, never cracked a book in HS - who also should have taken AP courses to develop the skills to learn more complex material) bomb out of college (full tuition scholarship and extra money scholarships, totally blown) and most likely will never return.
