how long does it take to use the free learning before upgrading
At time of posting, you can use the Free tier to browse the Cybrary catalog and access select courses and labs from most (but not all) Career Paths, Skill Paths, and Cert Prep Paths. To access any full path, you will need to subscribe as a Cybrary Insider Pro member or otherwise obtain a license through an employer with Cybrary for Teams access.
You can easily get to LEVEL 7 (xp)… I hope that gives you a clearer idea of how much experience you can gain
