Got approved by the Hillsborough County Development Board today! Waiting for registration for exam to come in mail. I have obtained all the recommended testing references and am already studying them. Anyone from Florida recently taken the Experian Irrigation exam? Just looking for any helpful hints about the test not any answers. What is the hardest part of the test? I don't think I will have any problems with the Irrigation part of the exam but I am concerned about the Bidding, Business Law, and OSHA parts.
