This is the first time I’m hearing about it (maybe because it is European?), but reddit mentions they have coordinated advertising campaigns posting on forums and reddit with positive reviews, so that makes it of dubious intention (i.e. focusing more on marketing than actual content). Although it is probably no more of a scam than the computer science tech bootcamps out there.
Some sleuthing on LinkedIn found one of the instructors listed for the Electronics program, who doesn’t work there anymore say this about his time developing the “curriculum”:
“Although they were not the subjects I knew best, I had to read a lot to do a good job. It was the first time I had to interview people under my supervision and it was a very enriching experience.”
It could be that they have grad school / research assistants developing a curriculum that is outside their domain of expertise, instructors are probably paid once to develop the online training material and then move on to another job or actual university… It’s hard to know without seeing the actual material covered.
You could definitely put together a cheaper self-study program with a combination of CE, Udemy, EdX/Coursera, etc, or look into local technical vocational schools.
Do you have specific goals for specific subjects? If you don’t know where to start, start with this website’s projects or find an intro to Arduino course and start building real things to get excited and figure out what domain of “Electronics” you’re interested in. Kody on this forum is going through the Learning the Art of Electronics lab book so that is also a place to start.
If you’re looking for more of a traditional university style course to get started, the MIT 6.002 Intro to Electronics course is available for free on EdX.org (also on MIT Open Courseware) – you’ll build both digital and analog circuits, and MIT prof. Anant Argawal who teaches the course also founded EdX, so he is very invested in delivering quality education.
