"This open-access course is directed at those who are already familiar with C and object-oriented programming" ... but not C++
That's a very, very small target you're aiming at there.
"This open-access course is directed at those who are already familiar with very old C++ and object-oriented programming" ... but not modern C++
Written this way, the target is bit larger.
Regardless, it is a very comprehensive review for C++ programmers, and even intermediate ones will probably see new material there.
