IGCSE RELIGIOUS STUDIES HELP!!

Hi guys!!! So I have IGCSE 2026/2027 may/june papers coming up, and I just picked up Religious Studies. I want to do Christianity and Judaism, but I can barely find any study sources online, and Save My Exams won't allow me to access all the notes till i pay. Does anyone know where I can get free, accessible study resources for Religious Studies in a completely legal way?
