some Issues with Udemy

Udemy offers self-paced courses but many of the courses are so short they are effectively tutorials. Free courses constantly upselling there paid offerings to users. The assessment is often inadequate . There is also very limited video captioning and language support. A lot of Udemys content needs more careful vetting.
