Ask HN: Best office/general computer skills course for my mum?

Hello HN,

My mum is not very tech savvy but wants to improve her skills. Her expectations aren't very high: she wants to be able to use office, do basic internet searches, use social media and generally feel more comfortable on a computer.

She has some free time now and has asked me to find her a good course on using office and also the aforementioned general computer skills. Also, she's living in Equatorial Guinea so there are no local courses there, meaning it must be an online course. Can anyone recommend any free or paid courses on this?
