Spent the past three days in a certification prep course. This course used accelerated learning principles, content chunking and frequent quizzing starting with a pre-test and culminating in a simulated certification exam. My confidence is higher and the study plan leading up to the exam date makes sense. Although pricier than other options, this provider has a good reputation from those in my network and the facilitator was excellent.
As with most certifications, you have to erase reality and think from the pure world of the certifying organization. I'll update as I move through the study phase into exam phase.
