I personally took Modern Studies, and not History, all the way through to Advanced Higher and I would say the AH is a particularly good course for people looking at doing law (I ended up doing a 6th year dissertation on penology and using some of the same textbooks in first year). I think either class will do you brilliantly and what’s most important for applying to law is your grade rather than the subject itself.

Generally you should stick to serious subjects and do make sure that universities will accept them in advance. The biggest tip I would give to anyone to avoid repeating the mistakes I made in applying is to research things early on. I pretty much stumbled into law and it would have been much less stressful to learn how it works in advance.
