Four Corners Upward Bound Math and Science serves 9th through 11th grade students who are low-income or first-generation college students from the following Arizona high schools: Coconino, Greyhills, Holbrook, Many Farms, Monument Valley, and Tuba City. Participants complete college-prep assignments by mail throughout the school year. Successful participants are invited to reside on the northern Arizona mountain campus for the 5 weeks and take classes 6 days a week for the summer component. Rising sophomores take Biotechnology and Latin/Greek, rising juniors take Chemistry, and rising seniors take Physics. All students also take Mathematics and English. The rising seniors also visit colleges for an additional week. Students are recruited during the 9th and 10th grade and are invited to return each year based on their performance.
