I don't know who is teaching or when.  I just presumed you wanted another instructor, and I can offer you a name I know.   There are also others who can keep you alert and make the course a truly enjoyable learning experience.  Ed is a very dynamic speaker, and is a past president of the AWS.

You should also realize, that the student audience often thwarts the instructors ability to keep the course on track.  One instructor recently had two members of the class who constantly interrupted and disrupted the class.  There was little he could do about it without getting rude and crude.  It is not always just a "bad" instructor that is to blame for failing to control the class! 

One more thing.  It is my opinion, that people who absolutely need this class to pass the CWI Exam, are not ready and are probably not qualified to be CWIs. 

I suggest you read 20 pages of the welding symbols book, the definitions book, and the inspection hand book every day. (Each Book).  When you are done with each book, do it again.  Read two chapter of your chosen code book every day, and repeat when you are finished with the book.  Take the mock tests, and look up the source of your answer for each question and read it, and the paragraph before and after it..
