I am very nervous whether my GCSEs will put me down if i apply to imperial college for chemical engineering. My GCSEs were 4A 2B 4C with A in english language and chemistry. I heard its very competitive and that my GCSEs will put me at a disadvantage. The a levels i chose were maths, chemistry, physics,electronics and economics. Obviously I'm aiming for 4As at AS.
Are GCSEs good enough and if not, what could i do to increase my chances of being a successful applicant?
P.S. What if i dont have further maths?!
