A carefully set-up experiment in methods of conducting examinations in physics is being carried out. All of the variable human factors have been eliminated as far as possible. Students hearing the same lectures, studying the same textbook, and writing the same examinations are pitted against each other: one group using their books and any notes which they care to bring to class with them, the other group using no notes or helps of any kind. The results obtained in this experiment are expected to shed definite light upon the much discussed problem of the aid or hindrance of books during examinations
