I’m going into year 12, and just finished GCSEs. Firstly I wanted to ask if my results are high enough to apply to Russel group unis such as imperial and Oxford, my results were 9998888877, and I am going to take 2 further GCSEs in year 12 (my home language). As I got a 7 in maths should I retake it in year 12, or will a 7 in maths affect my application to Oxford?
