To me, welding symbols were a source of difficulty. Simply because unfamiliarity of certain proceedures ie. Projection weld for instance is one I have yet to encounter in my work... and face it, most detailers/draftsmen do not adhere to AWS methods and symbols.
Part B seems to get a lot of people and can be confusing if not approached with the insight to the answer they are seeking. Make sure those funky plastic weld sample have not been compromised! Bring your own flashlight (to me the supplied LED is too "soft" of a light and washed out detail for my burned out eyeballs). Do not over flag your code book! Maybe 10 or a dozen at the most or you will just confuse yourself on test day.
Oh, don't forget your calculator! I had to borrow one from the front desk clerk (it was junk and ended up runnig most calcs longhand...time consuming, but do-able).

well as far as flagging the book. i didnt flag it at all, i just got familiar with the glossary and when they ask the question you can pretty much know what area to look in. i didnt highlight anything either that will confused you as well cause just when ya think ya got it. its on the next line that you didnt highlight. so no highlight for me so i read through until i know it was the answer word for word. and fundementals is the only thing you have to know and remember. the rest is in the book. the spec (part B) is what ya really have to pay attention to the answers are very very very close the the others, and could cause you to think the wrong one is right. so read all the answers before you make your choice. these are the steps that i took and i got over 75% on all the test and total average of all was 80% so i say it worked pretty good for me. to say that was the first time i went take the exam. "one shot one kill" oh yeah pay attention to the as detailed and the as fit up cause they could get ya if ya dont add them on some occasions. and good luck say ya prays and dont drink everynight. i had a few drinks right in the middle to kinda ease the stress but that was it. one night of tesion release and back in the saddle again.

This is for Juan.  I'm sure everyone has differing ideas to help you out but here are my opinions.  First and foremost, read every answer to make sure you find the BEST answer.  Right off the bat A might look like the best answer but then you read D and it is even more fitting.  They WILL try to trick you, especially on Part B (I had to retake Part B).  Personally for me the practice test for the fundemental section was not that helpful even though I knew it inside out.  However, the opposite was true for Codes and Part B.  If you can get to where you do really well on these two practice tests it will help immensely.  Be able to identify undercut and/or underfill because you will be asked about it on Part B probably more than anything else.  Last, I don't know what you do in welding right now so this may or may not help.  On Part B there will be pictures you have to identify.  On my test they were pictures of different kinds of NDT's.  They asked not just about MT or PT but what type of tests were they in that field, such as angle beam testing.  I do only visual testing so I was pretty unfamiliar with some of that stuff.  In the class I had this stuff was not even mentioned and in the Fundamentals textbook it is mentioned in passing but you take the test and sure as hell, there is 4 or 5 questions on it.  If you are unfamiliar with the NDT's and the different tests within those tests like yoke or angle beam, etc. then get on the internet and look them up.  Be sure there are pictures showing these tests.  Good luck. 

well i tested 1104. we kinda got a big flour job going on right now with piping for some modules, but most of my work is usually d1.1

where do yo find what glossary? i am not sure as to what glossary your talking about. as for the info on part C its the code book if you have what ever code book you plan on testing to, thats the info you need.

yeah i went to the seminar before. it helped with a few things as far as nde goes cause i was kinda blind on some of the nde. i was like what is that? and poof like magic some of them were on the test. so i would say if you have the money for it do it. cause it can help. when are you scheduled to go? mayeb you can try Real Education they are pretty good they smash over 1500 questions in your head before the exam. Gerald and Linda Taylor. i think its abou $1000.00 for the 7 day seminar, somewheres in that area, but if i were you i would consider it cause it helped me pass. good luck
