what is a easy way to learn the capitals and countries of latin america, south america and of the caribbean sea?

I have to know all of them by thursday.

I am from Australia and am planning a trip to Mexico and South America in a few years. I am wanting to learn a language but am unsure if Spanish or Latin American would be more beneficial. Any suggestions

If latin is the language of ancient rome, then should we start calling Italians latinos and latinas? they are the real latin people? If not, then the romace laguages are spoken in several different countries besides south america including north Africa, france, and romania and so on... Why arn't the people from these countries considered latina or latino? I think this world is confused. Please help.
