Set up the instrument. Get it level. Shoot the gradestick. Know what the actual elevation is. Subtract the actual elevation of the grade you want from the elevation of the benchmark. Add the amount you shot on the stick at the benchmark to the amount you deduced. Shoot the stick at the point you want, and tell your helper to move the stick up and down till you get the right # in your sights. Pretty simple once you get the hang of it. I'm 19 and can do it so...
