What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.
Some of the instructional embedded Youtube videos make use of Google Analytics cookies. These cookies are used to track video viewing activities by website visitors. This data is processed by Google outside of the EEA (European Economic Area). This means that we ask your consent to use these cookies. If you chose to disallow the use of these cookies, the access to our website will not be impacted. However, it may be possible that you will not be able to see the embedded Youtube content.
