Typo in Writing Sample

Hey everyone,

So I just wrote my writing sample (my test is tomorrow) and everything went really well, I had strong arguments etc. But with 5 seconds left, I notice a rather important typo (just the misspelling of a word) in the FIRST SENTENCE. I tried to fix it, but had no time. It is definitely clear what I meant, but I kind of feel like my world is ending right now. Anyone have any words of advice/ reassurance?
