Arts, Letters and Science 1. Mathematics 52, 53 and 54 are prerequisite or parallel to Physics 61, 62, 63. 2. The series of physics courses 61, 62 and 63 begins only in the autumn quarter. 3. Some physics and calculus are prerequisite to the engineering courses 150, 151 and 152. See the course descriptions for details. 4. Physics 63 and Mathematics 54 are prerequisite courses to all junior and senior engineering courses. Mathematics 51 should be taken during the freshman year so that Physics 61 can be scheduled during the autumn quarter of the sophomore year. It is important that a mathematics course be taken every quarter of the freshman and sophomore years. In many cases a student will find it advantageous to take a mathematics course during the summer between freshman and sophomore years in order to begin the physics series in the following autumn quarter. Area Requirements—Area requirements for engineers differ significantly from those for other fields of study. Engineering students should consult the catalog of the school to which they plan to transfer, and also their advisor, concerning area requirements. Courses of Instruction 1.
