WWHHOOOAAA there Hoss. Way overboard.
Several of those are just two day break downs of the Seminar Week pack. You don't need them separately. Now, since you can't take the exams for another year, I would recommend doing the online courses including, if you wanted to, some that are not included in the Pre-CWI course. When you take that they will send you the books listed as INCLUDED in the seminar week as 'FREE' handouts (we all know they aren't FREE, you paid for them with the course). I better check something out, I may have just misspoke. You may have to sign up for the seminar week AND the online classes to have the books included. But, you can take the seminar this year as well as the online class and then wait until next year to take the CWI exam. That will give you additional study time and preparation in your chosen code book.
If you have looked at the application process there is a list of suggested self study books that can be used after taking the online class and seminar to help you get a different and more complete perspective of everything involved with being a CWI. If you have not seen this list, let us know and we can get you the link or list so you can order what you need. Again, on that list are several of the books that are also included in the seminar price and you really don't want to buy duplicates if you have no need for them. The process has changed a little, but I bought ALL the books on the list and studied. When I took the seminar I kept those books and gave them to my son to study. He is also now a CWI. We give books away to new prospective CWI's whenever we see the type of person we want to help. Every time you take a course with AWS you are going to get the newest editions of several books that are part of the class/seminar you are taking. If it is a duplicate, give it away or sell it.
Before anything else, if you are not an AWS member, sign up now. Members get a 25% discount and if you don't do it early you end up paying for it with the cost of the seminar anyway. It can usually work out to be cheaper to do that right away and then start taking classes, seminars, and buying books.
Any other questions, just ask away. I know I didn't cover everything but that is a start.

1) Take all of the books that were supplied or referenced during your training to achieve an AS Degree and read them to understand all of the content.
2) Obtain the the AWS Body of Knowledge for the CWI and buy an AWS Welding Handbook Volume 1, 9th edition. Read the sections in the book...a few times.
3) Purchase a "Welding Inspection Technology" book and workbook and go through it. Answer the questions, closed book and check your scores. Go through it a few more times until you feel your understand the content.
4) Obtain a code book, any year, any code such as D1.1, ANSIi B31.1/3, API 1104 and read through it not really cover to cover but more learning where certain subjects are addressed.
Then after you have done some learning, decide if you need a course or just want to spend the money trying a test.
The above is an opinion only and based on only my experiences.
Keep in mind we all learn differently. I feel you should learn all you can about welding,inspection, codes etc... before attending a "prep class".
