The course itself is interesting and really recommend doing the in-class course, it definitely does all the difference, you will be surprised how much you can learn and practice in 20hours! There a few flaws with the course that I think it would be good for you guys to look over: There should be PDF handbook with all the units that we studied, so we can have permanent access to the information There's no way to know the correct answer if we fail the final quiz at the end of each unit. Besides that, the course is interesting and easy to engage with. I would definitely recommend!
