Global Politics HL/SL TIps

Hi,
I recently switched subjects from a subject to global politics, and I am finding it very difficult to cope with it. If anyone has any tips, resources, videos, or anything to study for global politics, please do share them with me. Some resources to self-study with. If anyone has links to detailed case studies or has full case studies, they wouldn't mind sharing them. Or just any tips and resources in general. Any help would be great
