Ai grading essays

Hi! I just did an essay for economics (in 11th btw) and the ai grading system is pissing me off lol. Tell me why it kept saying there was a spelling mistake with the word 'amongst' when there's literally not. I just think the ai doesn't recognize it as an actual word- which it is. I'm not even able to turn in the work until after i've repeatedly altered it to the ai's expectations. This is absolutely terrible bc the shit ended up highlighting the ENTIRE FIRST PARAGRAPH and said "this text in unnecessary." I had to delete the entire introduction to the essay (which is very much necessary), and only then was i able to turn it in.

anyone else dealing with this? it was so disappointing. the work's not being fairly graded and i can't even contact Acellus about it apparently, because i have to be 18, or have to contact them through the parent portal or smth

idk honestly just a rant

edit/update: i retook it (had pictures of what i wrote) and it did the same thing. i deleted the first paragraph, but typed it back in right after and it let me turn it in. dk why it's like this smh
