Linux-Course

Soft Intellect Linux Course

Recommendations for the course:

• Think about the material, try to explain to yourself or to your classmates.
• Make all the homeworks, they are really important, do not skip any.
• Ask me as many questions as you want, it's not about how you look, it's about your knowledge after the course ends.
• Experiment in your virtual machine, do not be afrad, that's why it's virtual.
