When you apply they will tell you to study books on the civil service exam, like postal workers and county workers take but thats bull****. Im an Operator and my test had addition, subtraction, multiplication and division.Mechanics as in gearing, ratios, and pulleys, some grammer and spelling. Basically anything from high school. Well good luck Gina and remember if you do become a surveyor, learn all you can. On my first job setting trench grade surveyors with 10 years experiance gave me measurements between 1 foot to 5 feet off and surveyd 5 miles that way. it took a few days and thousands of dollars to catch their mistake they guaranteed to be right.
