@mondaytosunday There is something newish called International First Year. This is what offers direct entry into Y2.
In theory it could be good, whether offered by a private provider or the universities themselves - the Y1 curriculum integrated with intensive English acculturation, etc. In practise I have significant doubts, especially concerning programmes offered by private providers.
To clarify; the vast majority of Overseas students take the IELTS exam and it is this requirement that is generally too low, especially in STEM. It is not uncommon that one must talk with a small group of overseas students together, with one translating. Of course a student with English that weak is all but cut off from confidential pastoral support. (There are ways to provide it, but few in this position will attempt access)
As time goes on some improve their English and others regress.
I agree with a PP that many of these students are academically excellent.
