EET was awesome for construction depth and also helped with the am portion as there is overlap between AM and Construction depth. When you sign up with EET Construction, you actually get access to their am review of the overlap topics.
From what I've heard about SoPE, it's more of a refresher course as opposed to an in-depth teaching course. So they may assume that you already know certain items, or the basic concepts associated with the problems. Before signing up for a course make sure you know exactly what you are getting and how the course is organized.
PPI offers a course also, but from reviews I've read on this site, the professors this last round were very unorganized, and 1 was even late for 1 of the courses. Also check the schedule to see if the selected course works for you. EET does construction mainly Monday and Wednesday nights. I think SoPE does theirs on Saturdays.
Definitely make sure you do lots of sample problems and freshen up on your geometry /trig basic equations. You'll be amazed at home many problems seem extra hard but can easily be solved using basic geometry, law of sines/cosines, and the basic trig functions (sin, cos, tan).
If you need, NCEES has a survey reference manual if you login to your account. They cover these geometry topics and can also help with the survey topics on exam.
