Questions
Everything you need to know
What roles does this prepare me for?
Each course targets a specific career path. Critical Infrastructure — our live course — covers CFT, CFE, EOT, CET, and Data Center Technician roles. The IT Hardware Technician track (rack & stack, remote hands) is coming soon, with more specialized tracks behind it. Every course is built around what hiring managers actually ask in interviews.
Do I need prior experience?
No. Every course starts from the ground up and assumes no prior data center experience.
Is it really all free?
Yes — everything. All courses, all lessons, every interactive tool, and unlimited practice tests with section-level score breakdowns and smart study recommendations. No credit card, no catch. Just create a free account.
