UC Berkeley has a reputation for rigorous grading policies. UC Berkeley College of Engineering guidelines state that no more than 17% of the students in any given class may be awarded A grades, and that the class GPA should be in the range of 2.7 to 2.9 out of a maximum of 4.0 grade points. Some departments, however, are not adhering to such strict guidelines, as data from the UCB's Office of Student Research indicates that the average overall undergraduate GPA was about 3.25 in 2006. Other campuses have stricter grading policies. For example, the average undergraduate GPA of UC San Diego is 3.05, and fewer students have GPA > 3.5 in science majors. UC Irvine's average GPA is 3.01.
