Not sure about Texas, but I think most state tests have a mixture of EVERYTHING from the booklet, from the most commonsense question like showing a picture of a stop sign, and they ask you what the sign means..... to asking very hard questions about things that were mentioned in the book, but you glossed over it thinking it wasn't anything you needed to know (my son did this with the SAME question about blind people --- TWICE!!!) Just study the book inside and out, and watch what other people do while they are driving so that you can see the book info see in practical use.
