Re: grades, grade inflation/deflation, expectations
http://projects.dailycal.org/grades/ may give you an idea of what grades look like in various subjects. However, it does not allow stratifying by lower versus upper division courses (though you can tell that “Biology” is all lower division, since upper division would be under other subjects like MCB and IB).
But if you can get the information from Cal Answers as a student, you may be able to find more detailed information.
