Check-in and security
Follow the current PSI bulletin for identity, appointment, and security rules. Expect the center to control what enters the testing room. Treat the process like a work site: follow instructions, ask before bringing an item, and keep personal materials outside.
The testing block
The exams are closed book, multiple choice, computer-assisted, and 3.5 hours each. Read the whole question, eliminate answers that conflict with the rule or units, and flag a slow item rather than surrendering the clock.
Before you leave
CSLB and PSI instructions explain how results are communicated at the center. Record what felt slow and which topic categories need review while the appointment is still fresh.
How to practice
Use the official CSLB study information, then practice in timed blocks. Keep an error log and review the rule behind every miss. Do not treat a practice percentage as an official CSLB passing score.
