There is no single, universally known real-world school called simply "PCA". PCA is an acronym that could stand for many things, and many schools might use those initials in their full name. To find out if a specific school you're thinking of is real, you'll need to provide more information, such as:
* The full name of the school: Even a partial name beyond "PCA" would help.
* Location: City, state, or country.
* Type of school: Is it a high school, college, private school, etc.?
With more details, I (or a web search) can help determine if the school exists.
