Overall good if you need the certificate to go abroad and already have teaching experience

I've been working with kids and young adults in academic settings for years and had taken pedagogy and linguistics courses in school, so this course was incredibly easy for me. I actually was able to complete it over one weekend, but I recommend giving yourself a week or two if you don't already have the linguistics and pedagogy background.

My bottom line recommendation includes the caveat that you will get the certificate, but should probably review the materials on your own after and do outside reading too, especially if you don't have a pedagogy background.
