Due to a difference of opinion between Miss Sullivan and Mr. Gilman, Helen was pulled out of school and was home tutored instead by Mr Keith. Mr Keith taught Helen Latin,Greek,geometry and algebra. Mr Keith acted as a guiding force to Helen.Initially he tutored Helen twice a week but eventually he began tutoring her five times a week. He was very forbearing. He,every class, revised along with Helen whatever he had taught her previously and assigned her homework which he later corrected. Mr Keith's tranquility in teaching made Helen's least favorite subject,mathematics, interesting. He trained her to think logically and critically instead of jumping to conclusions wildly. He was extremely gentle. Mr Vining,an instructor who was employed to make brailles for Helen sent an American braille for algebra and geometry the day before the exam. This caused a dismal Helen to panic as she was used to the English braille. Despite being distressed,Mr Keith did not lose hope. He took Helen to the college earlier than the reporting time for the exam and got Mr Vining to explain American braille. However one drawback of Mr Keith was he had relied too much on Helen's ability to solve problems mentally. Hence Helen had trouble writing the examination. Before going to college, Helen was tutored by Mr. Keith for another year. Mr Keith proved to be a wonderful teacher and had played an important role in Helen's life.
