If videos work well for you, professor messer has free video and study sessions available on YouTube. This can be found by searching his name on YouTube. If you enjoy reading, the all-in-one security+ guide covered the material well. Additionally, videos can be found on Udemy for a small fee that also provides related practice testing material. These resources proved effective for me and I was able to pass the remote test within 2 weeks of study that relied primarily on Udemy videos produced by Mike Meyers. Communities also exist on Reddit and around these resources.
