Phrase "mind you"

Hi teachers!!!

I have found an expression " Mind you" look at the sentence:

Dara failed his final exam. Mind you, he is a studied-hard person.

Is in this chance the phrase [color=red]mind you the same meaning to the word [color=red]but?

How to use this,[color=red]mind you, Phrase?



It doesn’t mean “but”. It means something like, “Pay attention, because I want to stress my next point.”
