I dropped a class. How do I report it to the UCs?

So I moved schools during my junior year. In my first semester I took AP Microeconomics and planned to take AP Macroeconomics in my second semester but I changed to a different school where AP Macroeconomics is only reserved for seniors. So I pushed back taking the AP tests for a year. So now this second school signed me up for AP Microeconomics as it’s part of their rule but I recently got the permission to drop the class. I don’t know whether or how this will affect me as I’ve already got some UC acceptance letters. Should I report it now?

Can you explain it more clearly? You already took the class for first semester senior year, why don’t just finish taking it? Also, reporting it now might result in your admission to be rescinded. But you definitely should report it and explain it to the UC’s.

Try calling the admission office of each UC to report this change and also make sure to explain your situation.
