It was a cool course. If there were more such courses, there would be much more good masters.
I work in a big company. My responsibilities include repairing equipment for employees. After the introduction of an electronic accounting system, everyone was given tablets, and I realized that I would have to study again.
I had no problems with radio engineering, but it turned out to be useful to repeat. I realized that a lot has already been forgotten. Yes, and there are still differences. I can’t say that I needed all this directly, but it’s useful, I think.
The amount of practice is just 5+. For example, before I had to solder very rarely, and now with the growth of technology at work, I needed to do this more often and at a certain level, which I did not have. In general, these courses turned out to be really useful (and this is rare, believe me, I was constantly sent to learn something at work).
Of course, it is possible to make a distinction according to the level of training, because on introductory topics, what is necessary for experienced people like me can be fit into one lesson. This is a recommendation, because people will come, and some are limited in time, they do not need to repeat this, but quickly get to know new architectures or learn how to solder normally. But this is more my opinion than a comment.
