Question 14 — A licensed guard may legally detain a suspected shoplifter under which condition?
You don't need more hours of training.
You need to know you're ready.
You're changing careers, coming off active duty, or getting back to work after time away — and a California guard card is the fastest legal path back to a paycheck.
The class teaches you the material once, then sends you to the state exam room to find out, in front of a proctor, whether it stuck.
Get the feedback before the exam does.
Finish a practice session and that evening an email is waiting, naming the one topic that's still costing you points — so the next session starts where the last one left off.

Use of Force is still your weakest topic.
You missed 4 of 6 questions in this area tonight. Run the Use of Force module again before your next session — it's worth 12% of the real exam.
See why an answer was wrong, not just that it was.

Question 22 — A guard may use the power to arrest a suspect:
Your answer: Whenever a crime is merely suspected
✓Correct answer: When a public offense is committed in their presence
Why you missed it: suspicion alone isn't enough to arrest — the offense has to happen in front of you, or you need direct knowledge it occurred. That distinction is tested on almost every BSIS exam form.
Now he knows why he was wrong — and that's the part that gets him ready.

A rehearsal room, not a classroom.
GuardPrep AI is not a training school and never pretends to be. It's built for people who already know the material and need to find out, in advance, whether they can prove it under exam conditions.
