Most American colleges and universities use the grading system of A, B, C, D

Most American colleges and universities use the grading system of A,B,C,D and F. An A is (36) worth four points,a B three points, a C two points and a D one point. Getting a (37) grade like a B-plus or a C-minus adds or (38) subtracts a few tenths of a point. An F is a (39) failing grade worth zero.
    A small number of colleges—perhaps about 20 nationally— (40) reject the traditional grading system. The Evergreen State College, for example, was (41) established in 1967 and has never used letter or number grades. Evergreen State is a public 4-year college in the (42) northwestern city of Olympia, Washington. It has more than 4,000 students,including 26 international students (43) currently.
    Evergreen State is organized into programs taught by teams of professors. (44) Each program brings together different subjects and extends in length over 2 or 3 quarters. Students are required to do a major research project at the end of each program.
    (45) The professors write detailed evaluations of the students, which are combined with evaluations written by the students themselves. Students also meet with their professors to discuss their work.
    The director of admissions, Doug Scrima, says employers and graduate schools like these evaluations. He says they show more about the quality of students’ work than traditional grades do.
    Most teachers would probably agree that traditional grades are sometimes unfair, (46) but professors at big schools say there is not enough time to write evaluations for each student in large classes. Some classes have hundreds of students.
