I have not taken these courses. These courses represent what I would term advanced insulin and diabetes education. They are of modest cost and are scheduled about every month. You have the option of pre-recorded or live. I presume you can do the pre-recorded anytime, but the live may enable real-time questions.
Looking through the course material, I would suggest that the book "Think Like a Pancreas" is a prerequisite. Get the book and read it thoroughly, if you don't understand the book, taking the courses won't be as beneficial. None of the courses goes over the basics, they start out with more advanced topics like Mastering Pump Therapy or Advanced Carb Counting. I have Scheiners "Ultimate Carb Counting Book" and suspect the topics are similar to what is in that book, looking at Carb factors, glycemic index, etc.
These courses appear to be an outstanding resource, I would hope that insurance companies consider covering fully these courses.
