My uni accidentally sent me my ‘degree classification’ even though I haven’t finished

Long story, but to cut it very short: I had a lot going on, so my uni allowed me to defer my final dissertation to August. However, they accidentally sent me an email saying that the board of examiners have met and based on my current grades, I can be awarded a 3rd class. (Without having to submit the dissertation). This shocked me because all of third year I have been getting mid to high 2:1.Second year was a mixed bag. I got 2:2’s on two fifteen credit modules, however, the other modules were all 2:1s. My final dissertation (which I have yet to submit) is worth 45 credits. I thought I was headed for a 2:1 but that email really worried me. Am I still headed for a 2:1 upon submission of the dissertation, do you think? It doesn’t really make sense and I’m really confused. It’s made me paranoid.
