Frequently Asked Questions
How does pricing work?
Pricing is per-learner. Each learner gets access to a specific course for a set period (typically 3-6 months), bought by the learner or with an access code from their institution. There are no site licenses, maintenance fees, or infrastructure costs.
Are there free courses available?
Yes. NDG Linux Unhatched, NDG Linux Essentials, and Cloud and Virtualization Concepts are available for free. The Linux courses are good entry points for learners new to Linux; Cloud and Virtualization Concepts covers virtualization fundamentals.
How does ordering for an organization work?
When you're buying for 5 or more learners, request a price quote. Once the approved quote or purchase order reaches us, we email you one access code per seat. Give each learner a code; they enter it when they open the course on NDG Online. The same per-seat price applies; there's no volume discount or tier.
How long does course access last?
Access periods vary by course, typically 3 to 6 months. The specific duration is listed with each course on the pricing page. Some courses offer multiple duration options.
Do learners need to install any software?
No. All NDG courses and labs run entirely in the browser. Learners just need a modern web browser and an internet connection, no downloads or plugins required.
