Extention english requirement

[sweet fatima]

Hi there,
Was wondering if someone can help me out thanks! Im applying for my extention and filling out the flr(m) form. For the english language requirement do i need to pass the a 1 test again or can i re use my trinity collage certificate i passed 2.5 years ago with my fiance visa to come into the uk.

On the form it says :

Are you relying on an english language test which was accepted with your previous partner or parent application, provide details below of the test taken.
IThere is trinity collage london option? I thought trinity collage london certificates were only for 2 years valid.

Thanks for you help
