CompTIA is now offering a $50 US beta exam (XK0-005) for their Linux+ certification. Regular exam price is $380 US. You can scheduled the beta exam from now through Friday, February 18, 2022. The results won’t be official until the exam releases in June 2022.
I scheduled my online exam for the last day to give myself two months of studying time. I got the “CompTIA Linux+ Certification All-in-One Exam Guide: Exam XK0-004” by Ted Jordan. I should pass since I used Linux since the late 1990s.
