bruh it's the holidays u can do whatever u want

some ppl are nice who knows free chem tutoring?

yeah prove that tho cuz i don't think it's explicitly stated in syllabus

It's not in syllabus don't listen to Bored Of Studying.

le hospital or sub in small values of x (neither of which are in syllabus i think)
