"wasnt sure a practice site could actually help with something this specific but dicocexam.com had scenario questions close enough to the real exam style that i stopped panicking about the post exposure medical care section."

"did the mock exams a few times before test day, timing helped alot since 2.5 hrs felt long. the risk transmission questions were close to what showed up for real. relieved more than anything, def worth doing a full practice run not just flashcards."
