This is an absolutely excellent supplement to Hans Orberg's "Lingua Latina" textbook, and highly recommended for anyone who has ever wished that Orberg had provided more detailed explanations of Latin grammar. This College Companion parallels "Lingua Latina" chapter-by-chapter and gives thorough and careful explanations of all the grammar covered in each chapter using sentences, vocabulary, and situations taken from the chapters themselves. Not only university students, but also people teaching themselves Latin on their own from Orberg's book will find the College Companion an extremely helpful resource.
