Holy fucking shit are they serious? Anyone who paid any money, especially two fucking grand for such a “course” is fool. It’s not even state or CompTIA recognized! Spend two grand on something that will actually advance your career in tech, eg Cisco certifications, not on Linux! Heck, I certified for A+, Network+ and CCNA for less than $2000! And that included the exams! If you want certification for Linux start with a Linux+ course, it will only cost you hundreds at most.
