I passed my exam!! Woohoo!! :) I work in Higher Ed, so even though I've used Salesforce for the last 5 years, I had a lot to learn to get ready for the exam. Thank you @Eileen Kingsley-Hamm for the Admin Prep class. It was *very* helpful. My other tip is to take practice exams. I took a few that were online (free), and then also took the one from Kryterion. They will help prepare you for the types of questions (structure, format, wording, etc...), and they helped me understand where my weaknesses were (which sent me back to Trailhead for additional studying/practice).
Good luck everyone!!
Achieving the Salesforce Salesforce-Certified-Administrator exam has opened new doors for me, and I have this PassCertHub to thank for its exceptional study materials.
