How accurate are practice dmv written exams?

Answer 1

Put it this way, these exams were made for foreigners(not in a racist sense) to be able to pass, many of these people do not speak english as their first language and grew up riding/driving on a completely different road system. You should have no problem passing this test. But which part of the test are you asking is accurate the driving or written and even then accuracy sounds like the wrong choice of words in this question please rephrase.
