Yes I am quite sure that is the case (hopefully). I completely understand where you're coming from because I don't want to waste time either. My School sent out a letter today clarifying the situation and it said exactly what I told you earlier. Whether the exam being GCSE or IGCSE doesn't matter because the exam itself is taking place outside the UK and your centre is also an International Centre therefore your exam, even if it is GCSE, is an international exam but does NOT make it an IGCSE, do you get me lol? I hope I cleared things up and also unless you have been given a notice otherwise by your school, DO NOT and I repeat DO NOT stop revising for your exams, think that your exams are still approaching and you have to continue revising for each and every one of them. Good luck, and if you have any other questions, do let me know and I will try my best to help you !
