IB subjects for LAW? Watch
I dont think there is any university in the UK that has a specific subject requirement for law (although some recommend english A higher of an essay based subject).
Law is a really vigorous and competitive course so it is recommended that you take math standard level and make sure that any of your 3 higher levels are a language B(it is often not considered as an actual higher level by some universities).
The subjects I'm taking:
History HL- really good essay based subject, allows you to practice writing and analyzing and prepares you for the lnat essay(or cambridge admissions test)
Global Political HL- keeps you up to date with current events, also practicing essay writing, helps for lnat (knowing about current events)
English A HL- just proves that you have good english language skills, also essay writing and analyzing, (for international students for some uni's counts as english language proficiency)
Environmental systems and societies SL
Arabic B SL
The SL subjects you choose arent really relevant to your application so you can just choose whatever. Make sure your higher levels are the best subjects you can choose and are related to the humanities.
At the end of the day any subjects you choose will qualify because there are no recquirnments which is great if you change your career choice in the middle of DP. However the subjects above are better suited to studying law as well as it looks impressive for an application as it shows dedication to the subject and your ability to preform well in university for law.
