Should I retake my disappointing as results?

Hi everyone,

For my AS levels i received BBCC-
History: B C, overall B
Govpol: B B, overall B
English language: A D, overall C
Sociology: D B, overall C

I constitently received AAAA mock grades ALL YEAR and was told by my head of 6th form my worse case scenario would be AABB. Due to this , i had my sights set on warwick.

Should i retake my AS year altogether in the hope on getting better grades to apply to warwick??

Thanks
