Just catching up with this thread today, and glad to see everyone is friends again!
Cloeycat Scots Gaelic isn't a good term as it combines the name of the Scots language (Anglic) with the Gaelic language (Celtic). It's most correct to say Scottish Gaelic, although it is genenally just shortened to Gaelic. Irish Gaelic is usually just called Irish, and Manx Gaelic is generally just called Manx.
OP, like Irish, mh and bh become a v sound in Scottish Gaelic, although depending on where they occurs in a word they can also be silent.
Gaelic isn't compulsory in lowland Scottish schools, but it's available as an option but it depends on availability, i.e. whether the school has as Gaelic speaking teacher. Separate qualifications are available in Gaelic for native speakers and learners. There are Gaelic-medium nurseries in Glasgow and Edinburgh, but I'm not sure about schools they can attend once they reach the age of 5. Perhaps someone else knows? There are Gaelic-medium schools in the more traditional Gaelic-speaking areas.
Scots doesn't get the same recognition or funding as Gaelic so is used far less in schools. In fact it was practically non-existent until recently, apart from learning a bit of Burns poetry every January, however it seems to be creeping back into use in schools, as a form of literature.
Glad you enjoyed the language link!
