Is America one or two continents? Recently, I have been reading many articles in english about different topics for improving my reading skills. One of the articles that I read, was about the Antartic and the author meant it as "the seventh continent". When I saw that, I thought there was a mistake, because all my life I've known that the Antartic is "the sixth continent". But it wasn't a mistake, if not just an "another view of the world". I found out that there are several ways of distinguishing the continents. In Latin America, we learn the six-continent model, that considers America as one continent with three subcontinents, but in most english speaking countries, people learn the seven-continent model, where America is shaped by North America and South America, two different countries. So,after all, if America is one or two continents, just depends where you are from.

Choosing a major I finished my two first years of university studies so next year, I am starting with my major. I didn't pass all my subjects because I had to eliminate one of them, electromagnetism. Anyway, I had enough credits to choose my major, and I chose geology. It wasn't a difficult decision for me , because I had decided it when I was in the high school. Most of my friends also chose their majors already. I'm very excited with finally start my studies of geology, and I hope this will be a great year.

Note about PSU PSU ( acronym for Prueba de Selección Académica) is the most important exam in my country. Each student has to enroll for this exam at the end of high school and everyone take it at the same time in a specific day. In the first day, students take the Literature test ( Spanish: Lenguaje y comunicaciones) in the morning , and Sciences test in the afternoon, wich includes chemistry, biology and physics. In the second day, students have to take the mathematics test in the morning and History test in the afternoon. Each test has 75 or 80 questions with alternatives and two minutes per each one, so it last aprox two hours. Three weeks later, the results are publicated. The maximum score is 850 and those that got it , are called "puntaje nacional" (spanish for national score(?)). This exam is all that you need for attendancing to any university. Then, universities do a list with all the applicants and those that have the higher scores, are sellected.
