There are a lot of study guides available in addition to Trailhead. I’ve also been using Focus on Force and Mike Wheeler Videos. They are helpful for sure; I’ve realized I learn so much better listening and watching as opposed to just reading. The added context and visualization help the processes sink in. A refresh on Identity and security today, as well as Standard and Custom Objects. I’m also close to moving up in rank on Trailhead from Mountaineer to Expeditioner….a few more badges and points and I’ll be there. This one has kind of crept up on me, which I guess is a bonus of being so focused on moving forward I was not thinking about other things I am achieving at the same time.
