My DD's got a place at Glasgow Uni starting in 2023. We're in England and she'll be 19 when she starts. She's a bit concerned that lots will only be 17, so she'll stand out. I've told her it's common to stay for S6 now and take Advanced Highers. Is that right though - ie new Uni students are mostly 18 now rather than 17? I don't want to tell her the wrong thing!
