The open book examination is the one area that you will not find a correspondence course to take.

You didn't mention which open book examination you took, so there is little I can offer for advice other than what I was told to do many years ago when I prepared for the examinations on my own. I was told to read the code three times. Once to find out what was included in the overall scheme of things. Then read it to better understand what is written. The third and last time was to learn where everything is located. After all, the open book examination simply tests you on knowing where everything is. If you have a fair idea of how the material is grouped together, you stand a very good chance of winning the prize.

As for tabbing and highlighting the book, don't go crazy. Tab the sections and tables with figures so you can locate them easily. Next, go through the book and write in "forwarding addresses". That means, everyplace you have a clause that references a new clause or a figure or a table; write the page where it can be found in the margin next to the clause. Next, beside each clause write the key words if it isn't already in the BOLD print heading the clause. For instance, in D1.1, clause 5.22.1.1 has a header that says FAYING SURFACES, to me that clause is addressing fit-up requirements, so write "FIT-UP" in the margin and in the INDEX under "F". Likewise, the table that lists "F numbers" for shielded metal arc electrodes is no in the index, anywhere, so you have to add it so you can find it easily when you need it. Notice I didn't mention "highlighting". The important stuff is already in bold print. Too many colors will only confuse you. If you do highlight, highlight the key word in each clause.

I prefer the D1.1 Welding Code because it does have a good index and everything is laid out with a reason. API is not as thick, but it has no index to work with. What ever code you elect to use, learn it's layout and the information, but don't try to memorize everything.

I would try to write a question on each and every clause in the code. You have to understand what the clause is saying in order to write a good question.

i am in the same situation as you.  i called aws and they said the 40 hours is very open, meaning anything pertaining to welding technology is acceptable.  i asked about osha training and she said it was acceptable, however on the job training was NOT acceptable.  i am a welding instructor and teach 6 hours a day, she said this would not work for the 40hrs.  if you have any other info on this let me know, i some how have to get my 40 before april 25 and have know idea where to get it.
