Uruguayan American School

An elite, small school in the city of Montevideo, Uruguay, full of rich Uruguayans, Brazilians and sons of diplomatics from every embassy. There is a lot of diversity, most people speak 3 languages or so.
You can probably sleep your way through high school and still get decent grades if you take all the easy classes, but if you decide to go for the APs be prepared to go to school everyday (including Saturdays and Sundays), and work like if every class was your only class.

Be prepared for SAAC (Southern American Athletic Conference) 90% of the people participate in at least one sport. Girls usually loose (anyways, they are hot!) but guys always win, specially in basketball.

When we graduate from high school, we usually go to prestigious colleges in the United States, but we will never forget UAS .
If you are not Uruguayan, UAS is the place to be.

A popular hangout for rich bethesda kids in the heart of the city. Before 8 there are private school boys and girls who think they're ghetto, after 8 the crowd gets HOTT. Lots of times you will spot druggies there...but not to worry, the MoCo PoPo is watching!
