I like Udemy that unlike other platforms, courses have an affordable cost (as long as you can get a coupon) and I must say that this is not a factor that intervenes in their quality, in fact that's what makes Udemy so good, that it has an excellent quality in its courses and you can take it for a very low price. I also like that the catalogue of courses you offer is very diverse, you literally find hundreds of courses available for almost anything you want to learn, there are diversity of languages and subjects, that's the best.
I like Udemy because I can have an autodidact learning, in an easy and safe way, this platform facilitates the learning to people from almost all over the world. I also like that if there is a course in another language and you really want to take it, then you can do it, since its subtitles are of high quality. I like that the classes are didactic and quite understandable, in addition the chat that the platform has is a great tool, because not only can you communicate with the instructor to clarify any doubt, but you can also communicate with your classmates without any problems.
Udemy is a great platform and it has really been a great support in my learning, however, I have found in the platform certain courses where it is difficult for me to follow the rhythm of the teachers, and these do not have a constant dynamic, sometimes they go very fast in relevant topics, and then they go slow in superfluous topics ... and in the worst of cases I have found teachers who do not comply with the established program.
I like this teaching platform because of the excellent software courses it offers from the simplest to the most advanced.
Udemy helps me because it's like having a private teacher within reach of my computer.
