LPS, Local Day School or try again for 10th grade?

Not sure if I am reading this correctly or not–are you saying that your son lives in the US now but will be able to pay home fees to a UK university instead of overseas fees? I thought the rule was you had to reside in the UK for three years prior in order to qualify for home fees. I would love to know if I’m mistaken on this rule/not reading it correctly, as I had assumed that was not an option for my own children.
