Hi. I am an EIT in North Carolina. I'll be sitting for the Civil: Water Resource and Environmental exam in May. I am looking at purchasing an online prep course. I've narrowed my decision down to the following options: 1. Engineering Education and Training (EET) 2. Civil Engineering Academy I'm looking for recommendations or firsthand experience with either prep course. If you've done one or the other and insight to share on if it was worth your purchase, please let me know. Thanks!
