of Business (1), College of Chemistry (5), College of Engineering (20), College of Environmental Design (4), College of Letters and Science (67), Rausser College of Natural Resources (10), and individual majors (2). The most popular majors are electrical engineering and computer sciences, political science, molecular and cell biology, environmental science, and economics. Requirements for undergraduate degrees are set by four authorities: the University of California system, the Berkeley campus, the college or school, and the department. These requirements include an entry-level writing requirement before enrollment (typically fulfilled by minimum scores on standardized admissions exams such as the SAT or ACT), completing coursework on "American History and Institutions" before or after enrollment by taking an introductory class, passing an "American Cultures Breadth" class at Berkeley, as well as requirements for reading and composition and specific requirements declared by the department and school. Three-hour final examinations are required in most undergraduate classes and take place over a week following the last day of instruction in mid-December for the Fall semester and in mid-May for the Spring semester. Academic grades are reported on a four-point, five-letter scale (A through F) with grade points being modified by three-tenths of point for pluses and minuses, save for the A+, which carries just four points. Requirements for academic honors are specified by individual schools and colleges, scholarly prizes are typically awarded by departments, and students are elected to honor societies based on these organizations' criteria. Graduate and professional programs Berkeley has a "comprehensive" graduate program, with high coexistence with the programs offered to undergraduates, and offers interdisciplinary graduate programs with the medical schools at UCSF (various masters and doctoral) and Stanford (MD/MPH). The university offers Master of Arts, Master of Science, Master of Fine Arts, and PhD degrees in addition to professional degrees such as the Juris Doctor, Master of Business Administration, Master of Public Health, and Master of Design. The university awarded 963 doctoral degrees and 3,531 master's degrees in 2017. Admission to graduate programs is decentralized; applicants apply directly to the department or degree program. Most graduate students are supported by fellowships, teaching assistantships, or research assistantships. Faculty and research Berkeley is classified among "R1: Doctoral Universities—Very high research activity". In fiscal year 2021, Berkeley's funding for research and development exceeded $1 billion. There are 1,789 full-time and 886 part-time faculty members among more than 130 academic departments and more than 80 interdisciplinary research
