I do not know how to answer this question because I do not know which courses you are talking about. I am a newbie here so this maybe something that everyone else knows... But, I do not.
But, it is the general case that for someone to answer a question they must know what you are asking about. So, to be able to answer you question, I would have to know where courses, you are asking about. It would help if you listed name of the institution and the URL along with the course name and the course number. Then some who has taken the course might recognise it and be able to answer your question.
But, as it is written, your question does not contain enough information to allow me to be able to answer it.
