This may be shit advice, but it may help.
I have a mint laptop and was also linux illiterate when I started. The way I did most of my learning was by googling (or duckduckgo-ing) “How do I [x] linux mint” and reading through stack overflow threads. If this doesn’t return results, (almost) any solution for Debian or Ubuntu will work on Mint.
In general, I just assumed that if I thought the computer could do it, there would be a way to do it.
I just had to go and check because I got my 2 year subscription for ~$0.75 a month ($1 CAD) back in April. When I check their pricing page while not logged in, it shows me that I can save 50% on my first year and pay $6 monthly.
