Maybe because in the USA, you don't "apply for a degree" at the undergraduate level? You apply to be at the university full stop, or at most an honors program.
So, you do modules or somesuch; presumably they have pre-requisites that work in largely the same way? Like for non high-school subjects "read chapters 1-4 of 'intro to $subject' and have a grade C or above on $exam"?
How do you manage expectations for courses/modules/whatever from both sides (teacher:student) without such things.
You simply declare a major/concentration and register for classes in the appropriate departments. If you get acceptable grades in those classes you are allowed to continue.
Isn't "declaring a major" almost synonymous with applying for a degree, presumably the declared major in this case would be "computer science", so requiring some programming knowledge for those declaring that major would be possible?
In theory can one easily go to a USA Uni based on relatively unrelated abilities - lets say history and cooking? - and leave with a degree in Electronic Engineering? If there are no subject-based pre-reqs why does one need to declare a major, or is that done later?
My UK degree was modular so I could have done something quite similar, but I was assessed for entry based on abilities pertinent to a nominated degree (not the one I ended up with as it happens). Modules still had [relatively loose, unassessed] pre-reqs such as reading particular books or understanding specific concepts.
By the time you have declared a major, you will have taken the prerequisite courses already. Some programming knowledge is required, but that can be acquired while at university, not before.
