If you have ever been to SourceForge.net and taken a look around, you have a good perspective as to the overwhelming feeling of the available paths and options for learning in the world of technology. You can also add taking a visit to Microsoft Learning
In technology we quickly learn that you take one bite a day of learning and keep learning. The pace of new has changed, but the fact that new is available has not.
We each have our own prefer consumption methods. Some like to listen to podcasts, some like to read and others require hands on practice. We also have brains that sponge up material when an animated storyteller shares their world with community forums or at conferences. There are many differences and many brains. We all get hit with all options.
So here is an interesting question: In your profile, do you have listed how you like to learn? Do you share this with others you are working with? Is it part of your career path?
When it comes to Dynamics 365 for Customer Engagement and anything Relationship Management my brain is like an onion. There are years of layers. I have been lucky, the Power Platform has matured with time rather than being replaced with time. Certain pieces have been replaced and that layer of onion has been peeled off and recycled, yet the model and great structure has survived the test of time allowing me to layer my knowledge and yet there is always more.
I must admit I have had a good time swimming in the training material for the newer exams. There are areas where it is smooth sailing and others where I have to shift left or shift right to absorb a new fact or two. There are areas that I will never use on any project, but are part of the core. There are other areas where I have used the material on all projects for the last numerous years.
It is just what it is.
For those tackling the MB-200 or any of the Microsoft Dynamics 365 for Customer Engagement exams. Mark has written a good summary of some great resources here.
And Remember Pass or Fail you will be learning and that is the point. Have more knowledge tomorrow than you had yesterday.
