US transcript LSE

i’m an applicant to history & politics @ LSE as an american, and just noticed that one of the entry requirements is a “minimum HS diploma GPA of 3.7.” My unweighted GPA is below this, but my weighted GPA is below. Will admissions consider whichever one is higher, or would they go with my unweighted? If I meet my other requirement (5 scores of 5 on AP tests) but am below the required GPA, will I be rejected even if my bad grades were concentrated in a year before I had even applied to LSE?
