Hopefully for the benefit of future test takers, I'm adding my review after signing up for this course and passing the survey exam in Fall 2016.
I must start though by saying that I don't think this course is for everyone. After failing the first time, I knew that I wouldn't do better without simulation exams. I can't say if taking a course without the (Computer Based Tests) CBTs would have yield the same result but I passed with this course which offered them. Here's my 1 data point for your analysis.
In any event, I borrowed a popular Survey review book and purchased a different one. They're the same. I studied with one in Spring 2016. Everything made sense. I learned a few things when it comes to calculations/computations and leveling which I knew nothing about. The rest was very easy and straight forward mainly because (no bragging), I'm pretty damn good at geometry and trip. Even won prizes back in the day.
When I took the test, it was a different beast. There were loads of equipment questions (down to the level of adjusting nobs on a specific tool) and loads of legal questions and a number of lengthy questions at the start and middle of the test strictly placed there to suck up your time. And the rest was easy. I wasn't ready for any of that. By the time I was out of time, I had 15 questions I was trying to click through to choose an answer and realize they were mad easy and all at the end. I figured if I were to take that test again, I needed a test strategy and needed to improve speed through actual simulation.
I signed up for CPESR. I didn't learn anything new (maybe 1 or 2 things) but I learned to practice a variety of questions at the end of each chapter. Essentially, their end of chapter quizzes, unlike the books, mix other chapters questions in there to keep you reminded of previous topics. I went through the 8 lessons over the course of 6 weeks or so. In the meantime, I got a number of material from someone on this board that I used to go over topics when I didn't feel like being on the computer. At the end of those 6 weeks, I started practicing the CBTs. I did each one of them at least twice. The course's author was really good at keeping in touch and was quick with answering questions when I had them. The course platform went through an upgrade and some things were not matching up.
I went into the test having practiced 4 CBTs at least twice (at least 20 hours) and took with me the review book they provided. Just like the first time, the test was easy but I learned to skip questions that were obvious time suckers. Still, I spend more than 2.5 minutes on each question. And honestly, I wasn't wasting time figuring things out. The whole time I was punching numbers in my calculator and barely breathing. The entire test, I needed 2 pages from my review manual for one conversion and to confirm something else. The majority of the test only required sin and cos, addition and subtraction. But there were so many steps to many problems and the answer options wouldn't put you in the ballpark without completing the actual calculation. By the time I had 20 minutes left, I had 15 questions I had not even looked at. I'll admit, I was so pissed that I had tears all over the damn desk. I felt like punching someone/something right there. I made sure to pick an answer for everything before time ran out. I walked out just as upset as I was the first time and didn't think I'd pass on my own merit.
How I passed, I don't know. The passing curve most likely has something to do with it. But, I think practicing those CBTs helped a whole lot with gaining speed. Using the CPESR videos helped with recognizing pitfalls. And, the practice quizzes and taking the CBTs multiple times helped with improving accuracy. I probably didn't answer more questions that last time but I probably answered them more accurately to make a difference this time.
Now that I've said all of that... I don't think this course is for everyone. If you already have a good survey background, have reviewed before but didn't pass or are really good with geo/trigonometry or a combination of those, then it's the right thing to do to self-study. If not, you might be better off with one of the other 2 offerings even if they don't have CBT components. If I had to rate this course 1 to 5 stars, I'd give it 4.5 as it delivered on my needs given my specific background. It is however very light, in my opinion, if it's going to be your first exposure to this topic and you don't have good math foundation.
I hope this helps someone down the road.
Cheers!
