I am still studying for this exam. My focus has been on completing a Udemy.com class on the certification exam (certificate of completion below).
I have also been doing some side consulting in my former profession (materials engineering). It takes up some time, but I can use the money.
The next step is to work through the Certified On Demand study materials and one day take the exam.
I'll probably intersperse some Trailhead modules in as well. I miss doing them; they can be addictive...
