Writing about class choices on the UC and Common App?

If you’ve seen my previous thread you probably know that my incredibly small school has cancelled several AP classes throughout the year, meaning that all throughout high school, I will have taken a total of 6 AP classes (I will be submitting 8 scores though). I recently spoke to a college planner, and based on the information above, he suggested that I write about the lack of AP classes in my applications. Where exactly would I write this? I know that the UC app has an ‘Additional Information’ tab under ‘Academic History’ but I just wanted to make sure that is the best place for it. Also, what would be the best spot for that information on the Common App? Thanks!!

Something like that would go in the additional information tab. I think the Common App has an equivalent place. Keep it short and sweet.
