University of California essay prompts

Do the UC essay prompts change from year to year, or are they kept the same? If they are kept the same, where can I find these questions? I want to get started answering them this summer to take some stress off during the first semester of my senior year of high school.

A few years ago, the essay prompts were changed so most likely they will remain the same for this year’s application cycle.

Here are the prompts and you pick 4 out of the 8: http://admission.universityofcalifornia.edu/how-to-apply/personal-questions/freshman/index.html

Thank you so much!
