How to remember a lot of stuff about different countries? How do I keep them organized?

Make word associations: take a country and think of something funny it reminds you of or sounds like and relate it to what you have to remember. Other than that you can just try and imagine yourself in that country and think about what would make most sense to associate with that country And I like making quizlets to memorize topics, make an account and type the info in, and use the flash card platform and just review review review. And if you search your topic on quizlet, you may be able to find a set of flash cards already completed. This happens a lot.

Start with the one that you are most familiar with then go on to different countries. If I was you I would keep then in order by countries in a folder.
