Last year’s animal science threshold was 4483, equivalent to a 4.033 GPA as recalculated for CSU purposes (10th-11th grade a-g courses, up to 8 semesters of honors +1 points). (The points are GPA * 1000 + 450.)

What is not stated on CPP’s web site is what the point value for local area is, so it is impossible to know how close you were to last year’s threshold. Of course, this year’s threshold can be different.
Chance of getting off the waitlist depends on how close you are to this year’s threshold, and whether the animal science major and the campus overall underyield.
