Hello! My name is Will, and I am a first year at Deep Springs College. Hopefully you will enjoy this as much as I enjoyed writing these posts.
    Deep Springs is a college located on a farm in California’s High Desert. L. L. Nunn founded the school in 1917 in order to help young men prepare themselves for lives of service to humanity. The school has 26 students, along with its staff, from a close community engaged in this intense project.
    Each student attends for two years and receives a full scholarship valued at over $ 50,000 per year. Afterwards, most students complete their degrees at the world’s most famous four-year universities.
    Things are pretty sweet here. For me, at least. I’m taking three courses this semester: politics, a musical theory and composition course with the wonderful Dick Dawson, who visits each Thursday.
    And there are many more guests in the desert—we’ve had a number of professors visit the college in the last couple weeks to interview for the position of some courses. While they were here, they offered sample classes, gave presentations of their research, and were interviewed by the Student Body. All of them brought new energy that is so important to a Deep Springs education.
Questions 13 to 15 are based on the passage you have just heard.
13. What is the speaker Will?
14. What’s L. L. Nunn’s purpose of founding Deep Springs College?
15. Why did a number of professors visit the college?
