CDL practice test

I've been practicing the tests on this web site because I'm wanting to get my cdl class b license. I was just wondering if the tests on here cover the whole range of questions that would be asked when I go to the DMV to take my actual test, or do I need to find out where I could get the complete range of questions somewhere else on the internet? Thanks.

 

Yes, I've only been taking the full tests and so you're saying that all the questions on here are ones that will show up on the actual written test at the DMV?

 

I live in Iowa so I wanted to make sure that any of the questions that are on the tests here on the truckers report forum are ones that would show up on the DMV tests or if not, then I need to know where to go to find where all the questions and answers will be otherwise I'm memorizing only a part of the questions I'll be asked at the DMV. I've heard that they have as many as 800 different questions that would randomly be put to you? Also, since I'm only wanting to get my cdl class b, the only other type of test I'd want to take along with the general knowledge test would be the air brakes test, right?

 

You obviously didn't understand my question. The link you posted was only a 65 question general knowledge test. If there are as many as 800 questions, where can I find the other 735?
