It seems like a lot of us are studying for the 2391 and I thought of starting this thread. We can become study budys, ask each other questions, answer them and give us all help and advice. I'm sure that people like Wilder, Sintra and all the other members (to many to list) can keep an eye on us to make sure we don't go off track. I'm not doing this so I can just pass an exam, I'm doing it so I understand as much as I possibly can. Ok first thing first, books. GN3, 17th ed, OSG and the Practical guide to inspection, testing and certification by Kitcher to me are the minimum. Any other books you can recommend please tell us, that's what this thread is for. I'm doing mine in Febuary, when are you doing yours? have you tried and failed the test? if so why and are you taking it again? What area do you need help in, can you help others in areas that you are good at? Maybe each day, post a question on here for us and give the answer the next day. Any ideas are welcome. I think this forum is the best place to learn from. The wealth of knowledge and experience that the members have is far superior than any college, we shouldn't waste it.
