Hi. I wondered what the transition is like from IGCSE/GCSE to Highers. Are the GCSE courses similar enough to National 5s for kids who've done them to transition fairly easily to Highers? I also wondered if schools typically start teaching the Highers curriculum once they've done their exams in S4? Or do they wait until the beginning of S5? My son will be moving to the Scottish system from an International School doing IGCSE at the beginning of S5 so just wondering if anyone else whose done that (or moved from England) could share any insights. Thanks
