If you have taken the exam in South Carolina, I 'd like to know your opinion on how detailed the questions were, how long you studied before the exam and if you passed or not. I picked up the study materials today for the core and category 3 exams. Cat 3 is for Turf & Ornamental Pest Control. SC has one core exam that covers pesticide & herbicide licensing. Cat 3 is people like me who will only be applying fert and weed killers. Study materials were $40. The exam fees are $75 & $25 respectively.
