Private life route English Test

[Fauxfur]

HI all,

I'm due to renew my visa on the private life route. It seems some things may have changed as whilst filling in the form, I was asked if I have done the English test. I am a bit nervous as I am doing this by myself without a lawyer. This is my third application and the first time this has come up. Am i required to have this test despite my private life route as I thought the test is only for indefinite leave applications? If this is the case, which test would it be, A2 or B1. So confusing!

Also I'm not sure if I am using the right form, any chance for a link just in case. I'm on the 10 year route via private life.

Any words of advice are appreciated. Many thanks.
