If there was a political pop quiz here and now, and you were quizzed on what political figures said as well as passages in different manifestos, would you bet on your success?
IMO such a quiz would be impossible for anyone but professionals. I have been following local and international news, but the amount of things happening on a daily basis is simply too much.
Also, constructing such a quiz would be impossible, picking questions would introduce political bias.
For example, Berney followers are likely to miss Trump quotes, even though arguably they are among the most politically educated groups in America.
To answer yoyr question, I believe I would score within the top 10% for most quizzes. But, there are a lot of quizzes I wouldn't get a single question right.
Why would it be impossible if someone isn't a professional? Anyone who has read a book could ask something like "which of the following quotes did Marx not say" followed by four passages.
As someone who is often pestered for not being a revolutionary, I am surprised by some of the answers to this.
Assuming you have read the book is the issue. Is it going to he Marx? Or maybe Judith Butler? What about other thinkers that write about race? What about anarchism, is Kropotkin out of scope? Should the quiz also cover market economies? What about Thomas Sowell?
My point is while I have barely scratched the surface, I have already mentioned a wide variety of authors which most people haven't read (some of them for good reasons).
