We are currently living in Peru. We plan to return to Scotland so that our two children (currently 12 and 9) can go to university there. However Peruvian qualifications are not recognised for UK university entry. So one possibility is to move to Scotland and join the state school system so that they gain Scottish qualifications. So the question is: In what year would it be best to join? Is it feasible to join in S5 and just do highers/advanced highers. Or is that too late? Is there anything else we should consider before we attempt this?
(More info in case it is relevant: They are academically reasonably strong, and native English speakers. We're willing to work hard at home to get them up to speed as necessary. Their current school follows something similar to the IB system (although not IB), i.e. not dictatorial teaching, more discussion-based or self-directed research within broad project areas, although with specific focussed teaching in key areas. Non-elite private schooling here in Peru is very common and affordable; there are probably more private schools than state schools. However I don't think UK private schooling is feasible for us.)
