Do I still stand a chance at an 800?

Last month, I took the SAT Bio-M test, and I know I got a question wrong (which I’m pretty mad about still), but I heard in subject tests it’s not scored like the actual SAT, so if you get a few questions wrong you’ll still be able to get an 800. I could have also gotten other questions wrong, so how many questions and I allowed to get wrong in order to receive a perfect score of 800?
Scores come out tomorrow, so I’m really nervous.

Thanks!

According to this curve (which will likely not be exactly the same because of curve equating) you could get an 800 with one wrong.

Remember that an 800 on biology is statistically harder than the tests with more lenient curves like math and physics so high 700s is still very good.
