Hello! I want to apply to CAPM, but I am not sure if I should become a PMI member or not. It is cheaper now, but I have to pay an annual fee. Could you please give me some opinions? Thank you

Hello! Sorry if this isn't the right group, but I'm kinda new to this. I purchased the ‘PMP Certification Exam Prep Course 35 PDU Contact Hours/PDU’ course on Udemy, but since I am still junior level, I plan to get CAPM certification first. Is this course still a good preparation for that certification? And can I use it as proof of course completion to apply for certification? Thank you to everyone who helps me :)
