Can I do this course from my phone, Chromebook or tablet?

The acceptable tools needed to complete a course

No, those are not acceptable tools. A laptop or desktop computer is required. The experience you are about to embark on requires certain speeds and a good internet connection to participate in this immersive environment. This has been seen and done repeatedly, often resulting in poor attendance and grades. No, internet-capable game stations are also not authorized. You do not need the fanciest computer, but an up-to-date standard laptop will do you just fine
