geotrainer is great for learning countries in geographic regions. What I wish is that it had similar tests for bodies of water, mountain ranges, etc. If you go into the description of each country, you will learn more about what rivers, seas, mountains form borders with surrounding countries, but it’d be a more holistic learning experience if there were either separate quizzes for physical geography, or if some major elements were included in the political geography quizzes. I really have learned a lot already, that would just make it even better.
