Our training course for Part B of the CWI exam is all you need to pass.
This course includes personal tutoring with the CWI who created the course. Every page has a chat box so you can quickly type in your question without leaving the course. The CWI will answer within 48 hours. You don't have to worry about not understanding the material because he will answer all your questions.
Also, the training includes two practice tests that are similar to the real exam. These practice tests are timed so they will prepare you for the time pressure of the real exam.
The course requires the following mold replicas and tools. They are sold separately at checkout. When ordered, we'll ship them to you so you can get hands-on practice.

Our training is fully online. You don’t have to travel anywhere. You can take the course from your home or any place that has an internet connection.

Our training works because it has many quiz questions. After each of the first eight modules, you will take a quiz to make sure you understand and remember the material.
Research from education experts shows that taking quizzes on a regular basis is one of the best ways to learn. The quizzes in this course are very important for letting you know if you understood the material. If you did well on the quiz, you can move on to the next module. But if you missed a lot of questions, we recommend reviewing the module again.
In the last module, we'll give you our best test taking tips and then you can take the two practice tests as final preparation before taking the real exam.
