I built a webapp with hundreds of SQL and python questions to help aspiring data scientists practice for their interviews. It's not really passive because it was a massive undertaking to write the questions/solutions and create the app. Now I got to market it by creating video solutions and posting it on Youtube. But I created it to help with my other side job which is teaching data science in the evenings at a university. https://platform.stratascratch.com https://platform.stratascratch.com
