Does my Unconditional Offer still count??

I am studying 3 A Levels at A2 and have firmed an Unconditional Offer, however after I have firmed, I am now sitting one of my A levels privately but with the same exam board and UCI number whilst sitting the other 2 A Levels with my sixth form. Will this affect my unconditional?

I'd tell them to make sure they receive your results correctly but it shouldn't affect your offer at all

That just gave me massive relief, thank you! Emailing them now.
