The EET Breadth course is well worth it, in my opinion. I know for sure that I wouldn't have been able to answer some of the AM questions on the exam without the help of the EET Breadth. The lectures have some background on theory, but mostly it is diving into the topic right away with questions. For instance, Samir covered construction and transportation topics really well, and it seemed like within the first 10 minutes there would be an example problem for us to think and work out whether it be construction scheduling, formwork, site development, vertical curves, etc. Amir covered structures and shallow foundation and his notes are very concise and easy-to-follow. Structures was not a strong topic for me in school, but Amir made it really simple for me, and those (ironically) were the first questions I happened to answer first on the test with confidence.
Nazrul covers water resources (of course) and also soil mechanics (effective stress, permeability test, etc.) and Materials 1 (compaction, soil testing methods, etc.). His notes are very organized, and he provides really useful formula sheets and summary equations at the beginning of the binder for his section. Samir and Amir do as well for their sections.
I completely understand that it is a lot of money, but EET helped me with over 85% of the problems in the morning. The key is to understand the concept, but once you do, you'll be really glad you go with EET. The organization of their binders also goes in order with the exam questions to make it much easier to navigate during crunch time (when it really counts).
I also think that EET provides you with the very best questions for preparation. They are just one notch harder than what you'll see on the exam, but the preparation is perfect, because you have to understand the "big picture" to get some of the problems right. Once you put the hard work in to the EET course, you'll take the NCEES exam and go "that seems easier than I thought!"
I hope that is helpful!
