Just answer the questions as best you can and see how you compare. Don’t expect to get 10/10 unless you really know this game inside and out! If you do get 10/10 (without guessing and without going back and forth into the manual or reference or strategy guides, then please email me and let me know).
If you scored 10/10 legitimately (I.E., your first time and without guessing), then consider yourself a Civilization expert. If you got less than perfect, you should check out the ANSWERS.
