I took EET water resources (breadth and depth) on demand in December, but I did not start study until EET started breadth webinar courses which were 2nd week of Jan. From Jan 15, my strategy was to study 2-hrs every day and watched VIDEO every weekend (say 8-12 hrs of study which includes VIDEO). Depth webinar started from 2nd week of Feb. Even I paid for on-demand, their strategy was/is let on-demand students join webinar session for problem-solving sessions, practice exams sessions and additional questions/answers session. Breadth portion was/is covered by three instructors. Dr. Najrul leads water resources (depth+breadth) and co-teaches soil mechanics and materials. he is very organized and I can say one of the best possible binders for PE exam. His binder covers more than 90% of PE exam questions (for me). I did not study any other materials other than EET materials (depth). Honestly, I could not get time to study everything of his binders, I wish I could. I did three practice test, one from NCEES, one from PPI and one simulated exam from EET. EET simulation was little difficult than other two. I got 72 in EET test. Dr. Nazrul told me I will get 10-15 % more in NCEES exam and I got 84%. I am giving all these details because I liked EET and I think you must get benefit from WRE course (if you can). I paid about $1000 for both breadth and depth as I got 5% discount as well. It was really difficult to make a decision which one I should join. First, I was trying to join PPI, but it was too expensive for me, >$2300, and had not in depth instruction or materials for WRE depth. Also, PPI breadth was taught by only one instructor which I do not fully agree that one instructor can be an expert on all. Hope this helps.
