Hello to All, I am new to this board and to irrigation. I am in class now that will be over August 11 and then I will take the (Texas) state test. I am told from the Water Management Specialists who I had to purchase the book from for the class that there was only a 20% pass rate. Does anyone know why the pass rate is so low and how much of that % is people dueing retakes. Is the test really that hard? On the other hand I am talking to a few co-workers about irrigating their yards for almost nothing just for the experience. Any sugjestions on what is the best manufacture to use or are they all pretty much the same?
