Homework for link building

Hello! So I am trying to apply for Junio Marketing Assistant right now.. Thought I might get experience if i put all of it to practice..

My homework is to choose 3 articles from their website - https://www.bitdegree.org/tutorials/

and choose any sort of blogs, websites and etc, which would bring the most SEO benefit to their tutorials.. My goal is that these websites would have bitdegree links in their content... The more better reputation websites links their tutorial, the better...

Any ideas how do I do it? Please help!!!
