Question: Which material has helped you with your studies the most?

Less for studies, but Wikipedia is fantastic for background reading for me. I learned a lot about cars, engines, planes and power plants over the years, and it is still something I dive in to now. It’s not so good directly for studying, but you can eventually find that you have quite a good background understanding of an industry or a topic as a whole
