The SNP put out a press release today about a 40% drop in EU students at some Scottish universities (and how that demonstrates the need to be independent and magically rejoin immediately).
The bit it doesn't say is that while these students were really great for universities as they are high calibre, each of those places is for a 'home' student (i.e funded by the Scottish tax payer).
And all home students must be considered equally so in very simple terms if you have a student from portree and one from Germany, the best qualified student gets the place. There's no preference for being Scottish because all Scotland and EU students were considered 'home'.
This was never widely understood (and wasn't even intended by the SNP as they didn't realise you can't discriminate between member states when they introduced the policy).
The drop in EU students numbers has eased the pressure on places and ironically without Brexit the issues around shortages would be even more obvious.
