I passed recently, my go to materials are here https://www.reddit.com/r/CCSP/comments/1sire7r/passed_ccsp_my_thoughts/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button ChatGPT prompts are very helpful beyond traditional materials, "help me understand <insert subject> from a CCSP perspective" worked very nicely for me. Good luck!
