Izziearmy could be studying Judasim for GCSE and could be researching it for 2 years.
Rosh Hashanah is significant in that it represents the time that God first gave Adam breath to live and because of this it is the beginning of the Jewish New Year which is when God is thanked for all the things he has provided for his follwers in the last 12 months. Jews usually pray of their hopes and wishes for the next 12 months. This is why special food with symbolic values are eaten at the first meal in the evening of Rosh Hannah.Sorry the only one I can recall is apple dipped in honey to symbolise wanting the following year to tbe sweet and good.
It is also seen as the day of judgement when God is said to take stock of his followers performance during the last year and he considers what the coming year should hodl for them. The time of judgement lasts 10 days ending in Yom Kippur. During the days of judgement jews will repent and ask God to forgive them for any sins they have committed during the last year and pledge again their commitment to him and that in the following year they will act and live their life in a better way
I can't remember much else but I rememebr this from when I did my GSCE in RS
