IAL Cambridge

Hiya im a UK Student currently studing A Levels from home, im planning to do History,Geography and Maths, for geography ive looked online and Cambridge is the only exam board that doesnt do fieldwork, however im not sure if UK Students are allowed to do IAL Cambridge could someone answer this for me please

According to their website, Cambridge IAL can be sat in many countries including the UK so sounds like thst should be fine
