9. Wolfram Alpha
Instead of doing hours and hours of hard work on a paper, using Wikipedia as a source, only to have your professor tell you that they do not accept papers that use “the world’s most accurate encyclopedia” as a source of information, get familiar with Wolfram Alpha. The majority of professors will steer you towards this site anyways, as it is a far more trustworthy source than Wikipedia. With Wolfram Alpha, you are now able to have access to the information you need at a moment’s notice.
