I am grateful to Learn Super Mart for the opportunity to let me write a Science series (How To Nail Challenging Science Questions That Many Students Fumble On) for them last year, 2016. I was, of course, elated that my series “nailed’ their top 16 Learning Resources in 2016. From their portal excerpt: “The series was quite well-received with it reaching more than 20,000 parents and students, and getting more than 3,000 Likes, Comments, Shares and Clicks.”
I would say that not what I wrote is popular, but rather, how relevant and current the topics were for the Science students then. It was also the examination period, so they might have found it useful.
