Language B HL vs Economics HL (Urgent!!!)Watch
I know that Econ HL is considered an easier subject in IB, despite the scores which one would be much more important in the future? Learning a second language or economics?
IB HL Economics is almost identical to SL Economics plus a very easy Maths paper.
Personally, unless you really need Economics (as in you want to study economics or finance or law, anything like that) I feel like having a foreign language is in incredibly important qualification in today's world. It gives you a big advantage when it comes to jobs, it proves that you're thinking about the world and multiculturalism / globalisation, etc. No matter what subject you're hoping to study in the future, you'll be able to 'show off' your foreign language subject in things like your personal statement or in interviews. It's really useful. In comparison, Economics, especially at IB level, could be exchanged with History or Business Studies or Geography, and it wouldn't really change too much about your application.
Having said that, it is probably easier to get a higher grade in Econ than it is in Lan B HL. So it would help to take a look at some uni courses and see what subjects they recommend, or require, for an application.
