I took this Mentoring Program to deepen my knowledge about C++. I was stunned by the huge amount of Videos and effort Rainer Grimm put into this program.
He does not only provide Videos, Examples and Exercises to explain the different Topics, he also provide further informations regarding those topics (Blog posts, Videos from CppCon etc).
One big advantage of the course is that you could wrote questions directly to Rainer Grimm or into the Forum and he will answer and explain also his answer in the weekly Q&A Sessions at the end of each week.
I could really recommend this Mentoring to beginners and also to intermediate C++ developers.
