Rogers, M. L. Stevenson General Prerequisites: Each course in elementary mathematics requires a knowledge of mathematical principles and an understanding and a working knowledge of the content of courses previously studied. The student's success in future mathematics courses is dependent upon this knowledge and understanding. For this reason, it is required that the student complete all prerequisite courses in mathematics with a C grade or better. Whenever a lower grade in a mathematics course is received, or the substance of the course is forgotten, the student should repeat the particular course. A mathematics placement test is required, prior to registration, of all students who have not completed the specified prerequisite courses within the past two years. Exceptions to this requirement are: 1. Those students who have completed equivalent courses within the past two years with a C grade or better at an accredited college. 2. By approval of the head of the mathematics department. This regulation is designed primarily for the benefit of the student and for the efficiency of the teaching staff. When the student is registered in the proper course, he has a reasonable chance for success—otherwise, he almost invariably fails. Arrangement to take the prescribed placement test should be made at the Personnel Office, Room 139 in Building No. 1. While the department aims to set up ways and means to see that students are registered in the proper mathematics courses, the primary responsibility rests with the student. Students enrolled in mathematics classes for which they do not have the required prerequisites may have their registration in such courses cancelled at any time. A student who fails to get a C or better grade in a repeated course may be denied the privilege to re-register for such course. Department majors should complete in the first two years: Mathematics 3, 4, 7, 8, 9, and 10; Physics 7, 8, and 9; and the general college requirements as specified elsewhere in this Catalog. It is recommended that majors who intend to do graduate work obtain a reading knowledge of French or German. Teaching majors or composite Physical Science teaching majors should consult with the head of the department and with the head of the Education Department. It is recommended that such majors include in their first two years Mathematics 3, 4, 7, 8, 10, and possibly 9; Chemistry 4, 5, and 6, or Physics 7, 8, 9, for composite Physical Science teaching majors.
