How similar are the practice permit tests to the actual dmv test?

so i'm getting ready to take my permit test. i already finished drivers ed school and i did really well on all the practice tests and i even did good on other practice tests online. i'm afraid when i go into the dmv that the test will be worded completely differently and i just want to ask if anyone's taken it and if it was pretty different from the practice tests. i live in CA. thanks!|||The one i took was pretty close to the practice tests that you take in the class. One thing to remember is to not freak out if you miss a question, just take a deep breath and when you're ready, go on. I live in Louisiana, so it might be different where you live. Good luck!
