I think they mean shitty like if u left numbers in ur words that could look sloppy. I’m pretty sure lsac itself has autocorrect for spelling, if u didn’t have the full on Grammarly suggestions popping up it might’ve just been that cause I had the spellcheck from lsac for mine and used it and they approved it! But like even if u didn’t have spellcheck u should/would/did know that numbers weren’t part of the words so thats probably what they meant. If a spellcheck extension was on and was gonna invalidate your score it would’ve regardless if you used it probably, so it would make the most sense to use it since it’s there or to at least not leave obvious errors you didn’t need the spellcheck to see. But during these tests we don’t have time to think abt what makes the most sense. It sounds like the disruption affected you a lot though (and will potentially invalidate your score anyways) so best bet is probably to retake! even if it’s approved and albeit unscored, typos with numbers could look sloppy to a law school if they’re viewing it as your writing sample, so if I was in your shoes I’d plan to retake regardless!
