One poor grade

Hi, im a british student so have A level and GCSE grades.

Does one very poor grade have a big impact on my application? I have 9 As and 1 A at GCSE, and am predicted two As and one A at A level. However, I got a C in my Philosophy AS level and even though the school appealed the decision it didnt go up. Do you think this will have a big impact on my application?

Thanks! And good luck to everyone!

You will get in.
