As for shop and English, you can get the answers for them from the internet if you're too desperate to do them on your own.
I agree with you on art 4, I remember it took me more than 10 times to complete it.
yeah i know i don't want to cheat if i don't have to
with the art, chemisty andshop it's the limited tries that makes it hard, you have 3 tries to do it, you come in cold, you don't have time to get used to it and that's it, fail and by the time you come to do it again, it's the same: i can't get used to it, so i can't do it.
it's not hard, it's just not giving a reasonabe amount of tries imo
