How did Helen write her preliminary exam?

Helen took her preliminary exams for entrance into Radcliffe College in the summer of 1897.  Because Helen was deaf and blind, she could not write these exams in the traditional way, which was by hand.  Instead, Helen needed special accommodations in order to complete her exams.  Helen had to use a special typewriter to write her exams.  This took away the anonymity usually associated with these exams, because Helen's were the only ones that were typed.  Rather than writing the exams in a room with other students, Helen was placed in a room of her own.  This was done so that her typewriter would not distract other students.  A guard was assigned to "prevent interruption." Mr. Gilman, the principal, read the questions and finger spelled them into Helen's hand.  Helen would then type her responses.  Mr. Gilman read and repeated her answers by finger spelling so that Helen could correct any errors.
