I am confused!!! Please help.....

I will apply for leave to remain visa on the 4th of August, paid the fee online two weeks ago and all the documents sorted. My question is, will they still accept my English Certificate which was taken from CIE Makati (University of Cambridge ESOL exam - KET) in July 2013?

My marriage visa is valid until the 2nd of September.

Hope someone will enlighten me on this one.

Thanks in advance.
