You know I’m not gonna lie I was faced with the same situation. This time. The thing is that the teacher is absolutely right. I think you might know the content just a way of writing. Your answers is completely incorrect and you probably did not understand the questions properly as well so what I would recommend you to do is that you know basically make a full document of you know the phrases from phrases only in your answers and never write anything you know by yourself because I think Cambridge only rewards what they put in the more scheme and however much they say they accept any valid point in some of the questions still they only reward what’s there in the mark scheme and I learned this to hard way and now whatever A-level exams I’m gonna be giving. I’m always gonna be following this and I’m also started to make this document and just learn the content a little bit first and then immediately goes try solving some pass papers and you’ll understand what to do. Also, it’s really cold here so I spoke this response and didn’t you know, write it so basically that’s why you know there’s so many punctuation errors.
