You need reliable internet that is fast enough to watch YouTube without glitching.
You will need a device with a browser and the ability to play YouTube videos. Most laptops and tablets are okay, but the browser needs to be up to date. iOs devices often have a problem with Safari, so Google Chrome works in those cases. It is possible to access the course material on a phone, but not recommended as your only device. Generally, the newer and more powerful your device is smoother things will run. If you are using a tablet we would recommend using a wireless keyboard.
For many courses, you need access to a printer to print out learning guides and project templates.
You need access to a word processor. There are free options, such as Google Docs and Open Office.
A reasonably up-to-date phone is helpful for creating pdf copies of paper assignments to hand in online.
