Helen Keller decided she wanted to go college and, therefore, needed more formal education than that provided at home by Miss Sullivan. However, she struggled with her classes at the Cambridge School because the school—and the world in general—was not accustomed to accommodating a special needs student. It was difficult for Keller to get textbooks in braille, so Miss Sullivan had to read all her textbooks and then struggle to summarize their contents into Helen's hand. Most of the teachers could not communicate with Helen through hand language, so Miss Sullivan had to write copious notes and then communicate them to Helen. A few teachers, however, did learn to communicate with Keller directly, such as the German teacher, so that offered some relief.
Keller was able to type out her exams on a typewriter and she passed them. She essentially succeeded in getting through the school due to the willingness of her teachers to work with her, Miss Sullivan's ceaseless efforts, and her own hard work.
