AP vs Admissions?!?

<p>Please Help…
My major is Electrical Engineering and I just got my admissions to UC Berkeley, UCLA, and UCI and I live in San Diego.
I also applied to UCSD, but surprisingly they rejected me!!
I called them yesterday to find out what is the reason and the lady said: “Everything is good, but… since I took AP Calculus in High School and passed it and again I took CalculusI in college, they can not add my units from ClacI to my overall units since it is ““Duplicated”” and I already got the credit for it!!” I like to know weather it is true or not? If it is true… why did other&better UC’s accepted me?</p>

<p>I found this online… What does it mean?!?</p>

<p>“Advanced Placement and International Baccalaureate units earned prior to high school graduation do not apply to the limit of 90 semester units or 135 quarter units.”</p>
