There are two parts to this Abrasive Wheels course, the theory which is this online course and then the practical which is demonstrating how to change a disc on an angle grinder in a Zoom meeting. The purpose of this online course is to reduce your classroom time yet still receive the information in a structured way and gain knowledge. We check that the knowledge has been gained and retained by having quizzes at the end of each of the 4 units, the quizzes have to be passed to carry on to the next module. If you fail the quiz you can retake it and if you want or need to you can review the module to be sure of your answer next time. If for any reason you have to logout of the course, when you log back in you will be automatically taken to the place where you left off so have no fear you won't loose your place.
