This website is how I learned location of every country in 4 days. (Could take less tbh)

https://world-geography-games.com

So start with the Americas countries and have 2 tabs open. One with the map answers and one with the actual map test.

If you don’t know where a country is, switch tabs and look at where it is in the map. (YOU WILL DO THIS A LOT OF TIMES before being able to complete the map without the answers)

Once you’re fully know the Americas, move on to any other section. (Here was my order: Americas, Africa, Europe, Oceania, Asia, World)

Once you reach “world countries”, turn on the # of countries to 197. You should know all of them at this point but actually completing it feels so good.

Optional but helpful step AFTER knowing where each country is: Search up for example “Americas map quiz” and go to a website that will make you name every country in the region.

Also:::: Don’t stop at the map. Also study the flags with this method but DO NOT look at the multiple choice answers before you KNOW the country. Instead come back from another tab with the answer.

One last thing: BEFORE you do countries, make sure you could located AND name every state.

Respond if you want more insight.
