We're Scottish and my DSs are Scottish state educated.
In Scotland you have one less year of schooling hence the fact that some people think first year is easier than a first year in an English Uni. First year replaces the last year of schooling in many cases if you go to Unis after Highers.
My son is applying also to English Unis and he will be the very youngest in his year, not turning 18 until the September although he is studying for Advanced Highers.
I think Advanced Highers are not very well understood in England. The course only lasts a year and is marginally harder than A levels in standard so they are considered more difficult generally than A levels.
Many English Unis admission departments don't understand this. Advanced Highers are also branded into A1 and A2 bands. A1 means over about 85% and A2 70% roughly. An A2 Band is equivalent to an A star at A level in UCAS points therefore a A1 must equal an A star star t*hat doesn't even exist in A levels grades.
Some Unis (UCL) insist on A1 A1 and A2 in Advanced Higher for entry into subjects such as law. This is crazy as it's equivalent to A star star x 3. Even Oxford only require AAB at Advanced Higher. My son has not even bothered applying to UCL for this reason and I doubt any Scots will.
Sorry about the bold. Whether I keyed in* a star it changed and I can't be bothered to retype.
