I have heard good things about EET. A friend of mine took it and showed me his notes provided by the class and they seemed very thorough. Because I’m from California, I do seismic on a daily basis and so I did feel lateral was more straightforward for me. Vertical was tougher for me that it covered broader materials and also a lot of more “school” stuff that I just had to brush up on. I would recommend a course because it pretty much figures out the schedule for you and I think that is already a big factor in terms of wisely distributing your time on each area. What I found useful too was the specification from NCEES, try to stick to that and don’t over spend time studying material that has 1 or 2 questions on. From the previous diagnostic I knew what I needed to polish on and I made sure I could do those problems comfortably this time around. Hope it helps.
