I am supposed to find and correct 15 errors in the passage, having trouble finding more errors. Many thanks in advance.

Why are many students choosing to pursue their college degrees using their home computers? Benjamin Franklin said, “A penny saved is a penny earned.” This principle applies to the American and foreign online student. Today, students choose to take online courses to save money on transportation, books, babysitters and supplies.

The fluctuating cost of gasoline in the United States is one reason online courses appeal to University of Phoenix students. They would rather cushion their financial nest eggs than spend money on replacing worn tires or risk icy road conditions.

Students also realize that a traditional college requires them to purchase numerous books. Online courses, on the other hand, provide the majority of their course materials within the virtual classroom. A student might save hundreds of dollars on textbooks during one block of courses.

Additionally, online courses are convenient for parents and caregivers. College students who are responsible for children or aging parents must rely on outside help. Online students are able to avoid the high costs of hiring people to take care of their loved ones.

Last, an online student does not have to purchase supplies. Pencils, pens, paper, erasers, backpacks, staplers, and paper clips are all needed in traditional courses. The online student needs only one tool to complete a college degree: a home computer. A computer is an online student's conduit to class and to all the materials he or she needs.

Franklin D. Roosevelt exclaimed, “Happiness is not the mere possession of money.” He wanted Americans to understand that the joy of achievement is the path to happiness. Even President Roosevelt would agree, though, that earning an online college degree is a financially wise decision.
