I'm a male in my mid-twenties who has tried and ended up not liking Computer Science and Chemistry. So, after taking a break from school I'm trying again for Petroleum Engineering. I have experience working in warehouses, restaurants, and retail stores. I read Wikipedia a LOT, specifically about the topics of Medicine, Biology, Chemistry, Theoretical Physics, and Religion. I also browse freely among other topics and regularly use Wikipedia for school work.
Wikipedia is often not a "trust-able source", and that is a good thing, because I find and delete random false/possibly false information all the time. Check out this fruit for a recent example. To fix this, just cite the reference that was cited in the article. in the case of many sources, pick the one that's relevant to the information. Uncited Sections cannot be used at all.
Wikipedia is great for learning about topics you have little/no knowledge on. I've been using it since 2006, when I finished high school and needed to learn more! It's definitely helped me pass a few classes I would've otherwise bombed, and it was Wikipedia that got me into chemistry, which I then studied for two years.
