180 minutes for 80 questions is a tighter clock than most states run - a little over two minutes a question. Speed at finding the right code section matters as much as knowing it's there.
Open book per the current PSI bulletin. The exam is written knowing you have the code - the skill being tested is finding the right section fast and applying it under the clock. That's trainable, and timed practice in the real format is how you train it.
Exam details change. Always confirm the current format, references, and code edition with the official PSI candidate bulletin before test day.
