What is the best way to study all my countries? RN I'm on Asia, and I've done USA, Canada (provinces and territories), Central America, Caribbean, South America, Europe. The thing is, IDK when I have my test, but IK that incase it comes in a week, I have to be prepared. Asia and Africa has 99 countries, and I can't study that fast. I need a fast, efficient way of studying. Websites are ok.
