I'm interested. and I'm sure others are as well! Out of curiosity, how many problems would you work per day?
Well, since you are interested...
For Vertical my main study reference was the Structural Engineering Reference Manual (SERM). This was my main reference for the exam as well. It has the bulk of the information you need right in this one book, in both ASD and LRFD. You need to weed out some lateral stuff if you are just taking vertical, but this book is mostly for vertical (in my opinion, see previous post for lateral uses). David Connor's book for Vertical AASHTO components. I think studying AASHTO would be hard regardless, but for vertical, where would you even start! David's book really hones in on fundamental topics discussed in the NCEES outline. The two practice exams (PPI and NCEES), and Structural Engineering Solved Problems, by PPI (I think, I'm not at work so am not looking at the references on my bookshelf). I spent months in the SERM. I would say over 100 hrs. I started in June before the April exam. There is just so much stuff to sink in. A co-worker said he would have gotten the SERM a year before the vertical and just gone through it a little bit at a time if he had to go back and do it again. You should know this book inside and out. I studied my Structural Analysis textbook from college for all of the fundamental structural analysis type problems. I am fortunate to have piers and mentors at my office who were willing to take the time and help me understand topics I didn't quite get the first (or second) time through.
So, in the beginning, Vertical, I went through the SERM and David Connor's book. 8-10 hrs per week for the first 6 months. I would study before work or after work and several hours on the weekends. If I was going through the morning style practice exams, that would be about 4-6 problems in an hour and a half. I took a practice exam 2.5 months out, timed, on a Saturday. Sunday I would grade the morning portion of the exam, break problems into categories (ASCE, AISC etc) and see how I did in each category. The following week I would start going through the morning problems. It was slow, probably took me a 15-20 minutes per problem because I was really trying to figure them out on my own, before looking at the answer key. If I needed to read up on something, I would take an extra half hour, find the code section, read it one or two or three times, then go back to solving problems. If I couldn't get a problem, I would walk through the answer key, mark it and come back to it the next day, repeat, until I could do the problems without looking at the answer key. The next weekend, I would grade the afternoon problems. This was my favorite part (oddly, I did enjoy some of the studying). I would see what parts I got right, and if there was a part I got wrong (of which there were a lot) I would re-work that part of the problem right then and there, following the answer key. I would spend at least 2 hours per afternoon problem this first weekend. I came back the next weekend and re-worked the afternoon problems, then graded them the same way. Not only did this help me learn the problem, but it burned the type of problem into my brain so if needed, I would remember where to go to find this problem.
While I did start studying very far out from the exam, it wasn't horribly intense and I don't think I got burned out (unlike for lateral). I will say, I probably spent 50 more hours than I needed (of 450). It took a good month to just get back into some sort of study habit (8 years since college). For lateral, I condensed my study to about 5 months out, and 300 hours (exactly, I kept track). I started studying for lateral 3 weeks after I took the vertical (didn't know yet if I had passed vertical). I would study 2 hours per day from about 11am to 1pm at my office and another 4-6 on the weekend. My employer was very generous to help work with my schedule in this way. It worked out very well to spend the morning getting my brain going with work things, then study for 2 hours, then finish out my day working. I tried to get 16 hrs per week for the lateral exam.
Maybe some people think it's a no-brainer, but repeating problems until I got them has been the only way I could pass this test. You may be one of those people who can just read something once and remember it, where it is in the code and it just makes sense the first time. But if you are one of those people who thinks you are one of these people, but actually are not, than you need to snap out of it. It won't work. You won't be able to just read through a chapter and example problems in the SERM and then expect to remember how to do something similar on a practice exam or real exam and get it right. You need to suck it up and do these things over and over and over. If you think, "I
think I've got this" than you don't know it well enough. You need to know it "backwards and front" as Barney Fife would say. One of my co-workers was fortunate to have a brain like that. He may have spent 150 hrs between the two exams. The other 3 co-workers to take this test spent up to 400 hours between the two exams. One of them still had to take each part twice. And then there was me at 750 hours.
Well, that is a lot of text. I hope it is helpful to someone, because my wife just glazes over when I start talking about this stuff. I may have over prepared, but I didn't want to take this thing more than once. Good luck to all. The test will rake you over the coals, but growth is always painful.
