From JDD Software:
The JDD Exam Simulator helps you pinpoint your strengths and weaknesses by asking you questions similar to those found in the actual exam. The questions will help you prepare for the actual exams.
The JDD Exam Simulator lets you manage your time and learn quickly by allowing you to study for the exams one module at a time, or lets you take a one module or full timed exam simulation that looks and feels exactly like the real thing.
The JDD Exam Simulator helps make studying quick and simple. When you take the real exam it should appear like the simulation that you have just been using and so you should pass first time.
Due to popular demand we have included both the JDD and 17th Edition Wiring Regulations exam simulations as many ECS candidates will evenyually need to pass the 17th Edition Wiring Regulations exam. Both programs operate independently and can be used on their own.
