3.5: Module 16 Competency Test No.3 Open Book
Module 16 Competency Test No.3 Open Book
Learning Outcomes
When you have completed this module, you will be able to:
- Within a five hour time limit, complete a written exam and the lab exercises without the aid of a key.
The AutoCAD 3D book was written with competency based modules. What that means is that you have not completed each module until you have mastered it. The Competency Test module contains multiple choice questions and a comprehensive lab exercise to test your mastery of the set of modules that you completed. There are no answers or keys supplied in a Competency Test module since it is meant to be checked by your instructor. If there are any parts of this module that you have trouble completing, you should go back and reread the module or modules containing the information that you are having trouble with. If necessary, redo as many lab exercises required until you fully understand the material.
If you are completing this book:
- Without the aid of an instructor, complete the written test and the lab exercise.
- In a classroom with an instructor, the instructor will give instructions on what to do after this module has been completed.
