Worried AF for my AP Precalculus Score

I’m an international student so APs hold weight for me, even a shit easy one like this.

HOWEVER, I did make the silliest mistakes ever that even a 4th grader would laugh at.

My estimated score at worst would be 46/64. Please help me understand the usual curve for Precalc.

I used a couple of calculators and most of them gave me a 5 but one gave me a 4. I took tutoring from an institute and the worst practise test I did was 44/64 and that too because the computer didn’t register 3 of my responses. My predicted score here was a 5 too.

Please help me understand!!
