I think my test was 25 and I got 20 right. All the ones I missed I was completely unprepared for and had no idea that anyone could even know that stuff. For example, one of them was something like "If carrying a load that extends beyond the rear of a truckbed what color flag should you mark it with?" and "How far behind the truck is the load allowed to extend?"
I got my license a few weeks ago and did fine. Been driving to school every day with no issues so far
