Free Preview Lessons – Try Before You Buy!


“Try Before You Buy” allows you to take two lessons and their quizzes at no charge so that you can see how the course functions. These are two actual lessons from the course.




These two lessons and quizzes are random.  There are 51 lessons total with additional printable handouts for more complicated information and enlarged drawings.  Some lessons are short and others are expanded for a comprehensive review covering questions on the IDEX California®.  The quizzes are formatted like those on the exam, but are not identical.  The critical study is the lesson.
