Today i made really really stupid mistakes on 4 big mark questions. I could have got them all right but made a slight mistake in the first or second step. For example In the suitable degree of accuracy I did 100 upper and lower bound wrong. In the sector question I got the radius for the 1/4 r and worked as its the total radius. For the probability question i did all the steps right but I didnt multiply by 2 at the start so my quadratic didnt work. Will I still get some marks for these questions or do i lose all the marks🥲

I just came upon a guy that sells poisons and jades there's a poison i wanna buy (guiseng) but it would take all my money. I was wondering if after I buy it I can only use it once or can I use it multiple times like it resets when I rest for example?

Guys how many marks can I lose and still a 9 or 8? I think I lost like 13 marks but id remove like 7 marks for things that I dont know or like mark scheme specifics so lets say I got 60/80. Is that enough for an 8 or a 9 or is it not
