Salesforce and Trailhead.
I have been a devout follower of Salesforce for the past 8-9 years and in the last 5 years earned a few Trailhead badges and attended the Salesforce 211 Administration Essentials for Experienced Admins (September 2016). I am using various study materials Trailhead which gives you a change to see if you have learned anything by passing the tests to give points and badges. I have passed the Salesforce Advance Administrator certification (including Certified admin) and Platform App builder.
A comprehensive on line course with short quizes at the end of each section along with links to current updates on each subject.
This is the goto for me passed my Admin 201 Advanced Admin 211 and Platform App builder exams with the help from the course materials and excellent tutor help.
