Grade/Curve?

Hi, I took an upper division psychology in the area of pathology (transnational relationship with family, relationships, and disorders i.e autism, depression, bipolar etc.) This class in the past 8 years thought by the same prof. the curve was 33-40% of students earn an A depending on the year. The syllabus did not contain what percentage was required to earn this grade, just a break down of the percentage of exams, assignments and participation. In my year, the curve was that 10%... Grade/Curve?
