Most courses are released on the App Model, i.e. you own access to the course for as long as it is live. Any updates, changes or improvements to the course are available to you when they go Live.
Some courses may be time sensitive, so will cease access on a definite date. In these cases, the payment page will clearly state how long access will be available.
If you are lucky enough to have an employer who wishes to purchase a site licence, you may have access to some, or all of the courses for as long as their subscription is active.
Likewise, if you see, or request, and we create, a series of courses which you feel would be of benefit to you and your work colleagues, please let your employer know about this option.
