@craftycatsinhats the ones which use non-interview stats post interview are:
Edinburgh - uses pre-interview score as 50% of post interview score, but as non-contextual RUK applicants need 100% to get an interview, that may not be a huge differentiator. However, they have a very high offer to interview rate for non-contextual RUK.
Aberdeen - also use pre-interview score for 50% of post interview. There may still be a bonus 5 points for achieved grades.
As others have said, UEA, UCAT is 50% of post interview score. He also gets full marks for the SJT virtual station.
There are several where the SJT is a virtual station (Sheffield, St Andrews, UEA, Birmingham, may be others).
Is he applying for any BMAT ones? Every year there are some very academically bright applicants (usually boys) who get 3 rejections and an offer from Cambridge as they are looking for different things, academic rather than soft skills.
For DS1 we also looked into a safety net plan of Republic of Ireland, where it is all done on grades and entrance exam, no interview. Sadly it was not an option for DS as he did not have a GCSE in a language.
