ibidPREP tutors are a special bunch. They’re not teachers in the conventional sense. They are writers and actors and artists and lawyers and physicists and public health experts and journalists and chemists. They are warm-hearted individuals committed to imparting the material, methods and attitude necessary to make their students happy and successful in their studies and their tests.
