I can think of s few situations where repeating 11th at a US BS could make sense. If you were an athlete in a sport where the college coaches might have a better shot at getting to see/know you, it could make sense. If you had a compelling reason to get an IBD and couldn’t do thst locally, it could make sense (but at a different set of schools.)
In all cases, it’d help enormously if you didn’t need FA.
You could probably do this – and should expand your list if it’s a goal – but you are going to need a good reason to convince someone to admit you.
