At the recent PSP Review Course conducted from 3 to 5 Dec 2018, one participant asked where can she find exam practice questions.  I acknowledged to her that there are not many sources of exam practice questions compared to other more popular certification programs. I shared with her about dexyuan.com where you can find PSP Exam Practice Questions written by me.  Try out the questions at https://dexyuan.com/index.php/asis/psp/
