It's intended, and designed, to be a wonderful chance to submerge yourself in another culture. The program is open to all majors but is aimed primarily at juniors and seniors.
Sophomores can sometimes get in on the action too, but only if space is available.
The fall session involves six class periods during which you'll get all kinds of good background information on Mexican culture and on the country itself. A 10-page paper is required when you return, which deals with the facts and opinions accumulated abroad and also the subject of cultural diversity. The middle session consists of three weeks between fall and spring semester when you actually go on the trip. The course meets the University's cultural diversity requirement. And although you don't have to be a Spanish-speaker to go, Spanish majors and minors can work out special arrangements with the Modern Language Department to get credit for the trip.
