- CWI Part A Test Taking Tips
Our training works because it has hundreds of practice questions. After each of the first 12 modules, you will take a quiz to make sure you understand and remember the material from that particular module.
Research from educational psychologists shows that taking quizzes on a regular basis is a great way 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.
At the end of the last module, you’ll take a 165-question timed practice test that is similar to the real exam. The questions of the practice test come from a question bank. Therefore, if you take the practice test multiple times, you will see different questions each time.
We also have demonstration videos showing weld processes and NDE (nondestructive examination). These videos will help you understand important concepts.
You’ll get 90 days of access with this course so you’ll have plenty of time to prepare for the test.
