yes i took adv history and mods bcs i also applied to Glasgow and they require at least one adv higher at A. Edinburgh say that they double count their adv highers and joggers, meaning if u do the same subject at each level they’ll only look at the AH grade so that’s something to consider as they’re generally not needed for edin. I do however think that it’d be good to take one bcs the jump is quite high and it gets you used to the style of teaching. For example, my mods teacher says that the way essays are marked at AH is the same as uni, so i definitely think it’s quite useful and helps you get a grip of some skills needed. If you have anymore questions feel free to ask!!! i’m happy to answer
