GCSEs in the European Baccalaureate

Hi guys, it’s my understanding that LSE does look at your GCSEs in your application. Has anybody here done the EB? If yes, do they have requirements for S5 grades (equivalent of GCSE)? They don’t say anything explicitly on their website, only their conversion of A level to EB, not even course-specific information… I am wondering because my S5 grades were so so bad but now I’m predicted 88/100 (~A*AA) and want to apply for history (supposedly more accessible).
