special aptitude tests recommended by the respective departments, and to consult with an advisor prior to registration. Recommended tests and inventories: It is recommended that all students of the divison take the Interest Inventory, Cooperative English Test, and Cooperative Mathematics Tests. Prospective engineers should take the Pre-Engineering Ability test. For admission to the Engineering Department, see "Entrance Requirements" listed under that department, Page 174. Special tests may be advisable in certain instances. See Mathematics entrance requirements, Page 183. Department of Chemistry Professor Alva J. Johanson; Associate Professors Ralph S. Gray, Head; E. Smith Murphy; Assistant Professor Spencer L. Seager. The chemistry curriculum provides a sound foundation in both the facts and principles of chemistry. Physics and mathematics are emphasized since these subjects are essential to an understanding of chemistry. Courses in English and foreign languages and an elective area insure study in nontechnical subjects and thus broaden the student's general education, enabling him to relate his study of chemistry to other fields of knowledge. Placement TestA chemistry aptitude test will be given and the results used with other tests to help determine the student's ability and his probable success in the study of chemistry. Students who make poor scores in the aptitude test will not be permitted to register for Chemistry 24 until they are better prepared. Proper arrangements to take the aptitude test are made at the Student Personnel Office. It is the student's responsibility to make arrangements to take this aptitude test before registration. Major RequirementsThe Department of Chemistry offers three beginning courses or sequences in chemistry. Chemistry 1, 2, and 3 is an elementary series of courses for those students who will take chemistry for one year or less, including students of agriculture and forestry. Chemistry 1 followed by Chemistry 3 is intended primarily for students of home economics. Chemistry 24, 25, and 26 is the basic beginning chemistry sequence for students planning to major in the physical sciences, chemical, metallurgical and geological engineering, medicine, dentistry, pharmacy, the life sciences, the teaching of science, and all others who intend to take more than one year of chemistry. Civil, electrical, and mechanical engineering students take Chemistry 24 and 25 only. The Department of Chemistry offers a major in chemistry leading to the B.A. or B.S. degree, and also a secondary teaching major leading to the B.S. degree. A maximum of 15 quarter hours in elementary chemistry 168 (Chemistry 1, 2, 3, 4, 24, 25, 26) will be accepted toward fulfilling graduation requirements. Students who major in chemistry should plan their courses carefully with their advisers. Departmental Major Forty-five quarter hours beyond Chemistry 24, 25, and 26. Required courses are: Chemistry 51 52, 53, 131, 132, 135, 151, 141, 142, 143, and 181; in addition, mathematics through calculus, and Physics 61, 62, and 63. An over-all average of at least C grade in courses taken in chemistry is required of all majors. A reading knowledge of German is required and a course in French is recommended. Additional courses in physics and mathematics are recommended for those students who plan to do graduate work in physical chemistry. Teaching MajorChemistry 24, 25, 26, 51, 52, 53, 131, 132, and 141; mathematics through calculus, and Physics 61, 62, and 63. Recommended: Chemistry 135, 151, and 181. Teaching MinorChemistry 24, 25, 26, 51, 52, 131, and 132. Composite Majors in Physical Sciences and General Sciences: See composite teaching majors in the Division of Education.
