Your info suggests you have made two posts, but,
WELCOME TO THE AWS WELDING FORUM!!
As Al's post hinted, it is ONLY a START!
If you have already registered for the seminar and exam I presume you have read the QC1 and B5.1 standards for qualifications and exam info and Code of Ethics for becoming an inspector. I would further suggest you buy, read, and study the referenced self study materials listed with the application process. Even the WIT book which you will recieve at the seminar as part of your package. Alot of material to cover in one week. Wise to know it ahead of time and be able to concentrate more on the code of your choosing while at the seminar and just review the general knowledge information.
Come onto the forum here and ask questions any time.
Just my two tin pennies worth. Good Luck.
Have a Great Day, Brent
