This course is great place to learn about the operating system security.

hay videos que presentan informacion equivocada y/o desactualizada.

the course contains an enriching information which helped me a lot

the voice clarity, some times the voice of different tutors is low

video quality should be improved, its very poor in several videos

The resolution of the images in the slides need to be improved.

expecting some hands on experience .despite that course is fine

For some presenters, some text is missing in the text caption

there were too many background voices and words weren't clear

S​ound quality not so perfect, however the content is great.

It should be more practical for the field of cybersecurity.

Basic knowledge of Operating System is enough for Begineers
