WELDCOME TO THE WORLD'S GREATEST WELDING FORUM hacksaw!!!!!This is why it is very important for you to get in contact with the local AWS section in your region...
One can get all types of necessary information from them as well as being a good place to network amongst your peers...
If your confused as to what Real is being paid for and what the AWS is being paid for, then contact both to get the details of each in order to clarify the confusion you may have.
One question if you don't mind me asking... How long have you already been studying and preparing yourself for the exam???
I ask this because, if you think you can go in and take the test without any sort of preparation, chances are that you may not fair well in the exam and just from an economic standpoint, it's not effective in doing so.
So, get all of your ducks in a row before you plan on taking the exam because 3 to 6 months of studying and preparing for the exam beforehand almost guarantees that your score will be far more successful than walking in blind to test...
Everyone in here gave you some good advice and suggestions so, I won't cover all of the bases since most of them have been already...
However, you must take the time to really learn all you can about measuring defects and discontinuities as well as determining whether or not one is indeed a defect or just a discontinuity... Learn how to read the notes in the part B handbook and get proficient in using both a micrometer and a vernier caliper as well as machinist's steel rulers...
Also, brush up on your fractions and decimal conversions as well as metric conversions... Familiarize your self with the many different types of discontinuities and defects as well as the various non destructive methods of evaluation...
There's probably more that I left out but, this is something you can chew on to get yourself ready and I'm sure more folks will chime in also so that's all for now.
The most important advice/suggestion I can give you is to take as much time as it is necessary in order to fully prepare yourself for the exam.
Respectfully,
Henry
