Making Friends at KCL?

-im thinking of firming KCL if i get an offer.
-worried because my grades are on the bordeline at A*AA on weaker subjects if i somehow get in may find it hard to make friends.
-i believe everyone will be on way above this for my course and therefore due to my lower predicted grades i may find it hard to fit in.
-is this true or false as i do tend to overthink about nothing?
- I am a very sociable person so making friends is important to me.
