I used to live in Portugal and followed the Portuguese school curriculum. However, this year I moved to the UK (due to financial problems) and now attending a school with Cambridge curriculum. The thing is that because I used to do the Portuguese curriculum, I never did my GCSEs. Currently I am on Year 12 doing my AS Levels, and I searched through many universities and saw that they ask for GCSEs.
Is it really a major requirements or is my argument valid? Or do I have to repeat the year all over again? Please help me
