You should proofread your chapters. Proofreading things is generally advisable.
did you notice something off? i generally just give it a quick scan and didn't find anything wrong, but i could've overlooked something
edit: rereading it i noticed it, i'm gonna give up on life now idk how i missed that
i think it's just a thing to do with the hour i'm doing them, maybe i should start doing them earlier in the day when i'm not coming out of a class or gonna go to sleep in an hour or two, or i just need to get back into the swing of things again, this happened far far far less before my stint with covid
