I purchased the All-In-One Software Development Bundle. The bundle was on a fantastic special which should have raised a few alarm bells.
I have completed a few of them now and they are incredibly out of date. The last one I completed was created in 2016 and for an IT course that would be incredibly old. I spent more time in Google trying to find how it is being done in the current framework than working through the course.
I have viewed a few of the other courses included and everyone I looked at was outdated.
The sound quality of the videos ranged between bad and mediocre. For the last course I switched quite often between the lecturer knows the subject to how can they miss that?
The accents did not bother me too much but it could be difficult for some people.
If you are a new developer, I would suggest against this bundle as most of the things you will learn has been deprecated and you will learn bad habits.
They do give out certificates which you can link directly to LinkedIn (which I don't) or you have to write a review which they will curate before you can get the certificate.
