No, there isn't. Even for financial professionals it's a very poor indicator of acumen and won't help you become a better investor.
Your best bet is mostly through academic textbooks. Youtube is full of charlatans and investopedia will only get you so far.
I saw someone recommend https://www.coursera.org/learn/financial-markets-global. I haven't taken this course, but it is taught by Robert Shiller (and is free).
There is this course, which I also cannot vouch for as I haven't taken it, https://www.coursera.org/learn/financial-planning. Illinois has a good financial planning program and the CFP Board is reputable for investor education. It may end up being too basic for you, but it is free.
Similar course through Florida: https://www.coursera.org/learn/family-planning
If you want to learn more about valuing companies, then Professor Damodaran at the Stern School of Business has some of the most widely available material for free. http://pages.stern.nyu.edu/~adamodar/
His classes are posted to Youtube and he also uploads slides and quizzes for each lecture along with the solutions.
