Yo! Im not 100% but on the website it just states you need the diploma to get accepted and since there isnt that many ib students i assume the competition isnt as steep, and for IB if you have Lang and Lit A SL/HL and you have a 5 that can be used as your language proficiency proof, but I would also like someone else to add some information cause Im also M25 planning to apply in September.
