Helllllppppp meeeeeee!!!!!!!!!!!!!!

I have an assessment for religious studies and science coming up and I am terrified. Does anyone have science AQA assessments for paper 3 and WJEC religious studies christianity paper....???? And even maths edexcel gcse paper 3??

Are these all for GCSE? If so:

https://www.wjec.co.uk/qualifications/religious-studies-gcse/#tab_pastpapers <- that's the link to all the RS papers WJEC have on their website
