My wife and I are trying to understand US vs. UK school year equivalencies. My step son is 14 and is preparing to take his GCSE's next year. We are thinking about a move to the US possibly within the next few years and trying to figure out strategically what would be best for him. One feeling is letting him finish GCSE's here before making the move, then, let him finish in a US high school to finish preparing for University. Or maybe we could just let him take his GED/SAT in US and enter college right away. Or should we move before his GCSE year so that we give him more time to transition to the US educational system asap? Also isn't it better to have him graduate from a US high school so that the US university will have an easier time bringing him in or does it matter? Just needing some general advise on this from anyone knowledgeable. Thanks.
