Do HavardX-get smarter courses really worth?

Hi all! I'm very excited since I started a new journey into Fintech - I've had a pretty fast learning curve so far, but I want to do the work on my own to keep up to date with info and validate my knowledge, so I found one of these HarvardX courses. Do you think they work? Does it also have any importance recruitment process-wise? I find it a bit expensive, but I'd like to hear your thoughts on that before making my decision.
