Patricia Hill lives in Freemont, Calif., and the mother of 14-year old Clark who is preparing to take his math challenge test soon was a harried parent until recently. Clark would often come up to her seeking help for math problems, some of which were too difficult for her to solve. She had almost decided to get a math tutor for Clark when she learnt about TutorVista Inc., an online tutoring outfit based out of India that provides for homework help, regular tutoring or exam help to students around the world including students from kindergarten to 12th grade.
