Preparing for the School Bus section of the IA DMV CDL skills test can seem overwhelming. You know you have to ace it to drive a school bus in Iowa, so your entire livelihood depends on it. You have studied the Iowa CDL manual over and over again, but you need to put your skills to the test to see if you have got what it takes to pass. You can do just that with the IA CDL School Bus Practice Test. With questions pulled straight from the official Iowa CDL manual, the practice test has the same type of questions that you’ll find on the official exam at the DMV.
Begin by using the CDL School Bus Practice Test to determine what you know. The 20-question multiple-choice quiz gives you the option of skipping questions that you don’t know. Skip all of the questions that you don’t know, making a note of the ones that you skip. This will allow you to assess your starting point. Then, you’ll know how much studying you need to do before you go to the DMV to take your test.
After you have your starting point, study once again. Study up, and once you feel like you have learned some more information, take the practice test once again. Skip the questions that you are unsure of again and then get your score. Continue to do this until you are comfortable with all the questions on the test.
