On fees, they don't pay in Scotland so other Eu state national (but not the English, Welsh etc) can go to Scottish universities free if (I think) they reciprocate.
(The other change (in England but I suppose not Scotland, so not relevant to the thread) is the new right for universities to take as many candidates as they like who have AAB even ( English A levels, not Scottish highers) above the capped numbers they are usually allowed to take in. That is going to mean if you get good grades in England you have a much better chance of getting into places which are better than others.)
How do we improve aspirations of all people? Show them examples. Give them mentors. Have high expectations for them. Set the clever ones in clever sets in school. Given them trips to see universities.
Do not though make those who are not really up to it think they should obtain a degree which may not be much use to them.
