I am currently in year 11 after studying all of my subjects in year 10, without taking any of my exams early. Since I am in a higher set (class) for maths, I was given the opportunity to study further maths in year 11 with my teacher saying that we would be going over the GCSE maths course whilst learning the new content from the new course. As I was unable to take my maths exam early, I could not get my maths GCSE over with and would have to remember the content until I did the exam at the end of the year. After doing a practise paper at the end of year 10, I achieved a B grade which I was happy with but did not think I could better next year if I was not going to study the course the following year. Although my teacher says that I would be able to remember the content for both the GCSE maths course and further maths course, I do not think I will be able to handle the further maths course as I did struggle with some of the questions given to us to give us a feel of the course.
So, I am wondering, to people who have either taken or dropped the further maths course, whether I should continue with the GCSE maths course and potentially get an A/A* at the end of the year or have the opportunity to get an extra GCSE but maybe not with very high grades?
