Lse course transfer

Hi! Im a 2023 applicant applying for BA Geography. I love the human geography courses and have particular interest in sustainability, historical geography and in particular geopolitics. However Im faced with a dilemma. Im wondering whether it would be possible to change course if I get in LSE from BA Geography (application :tongue:

lace of 1:9) to BSc IR and Chinese (1:11). I would choose it as my 5 choices but all my other uni choices are for Geog as only LSE offers this course. My personal statement after many drafts is all on geography and I dont want to affect my application by talking partially about IR. Im interested due to my Chinese heritage and would live the chance to study at Fudan.
