My company will reimburse for a review class (if you pass), so I took School of PE for SE Lateral last fall and am currently enrolled in the SE Vertical classes (decided to only take one component at a time). I passed Lateral-Bridges on the first try, so I will say that it was a worthwhile investment. It definitely helped structure my review. A few thoughts:
1. The class runs M-TH 7-10PM EST for 5 weeks straight (60 hours). As a working professional this is very intensive and left little time to do practice problems during the week, however one of the benefits of splitting up the exam is that I had my weekends to do problems (the other course component runs all day on Saturday). I also took advantage of their "on demand" option and started watching recorded sessions about a month before the class began, so it made digesting the material a little easier.
2. The course ends 2 weeks before the exam, which I felt was plenty of time to tackle the two practice tests (PPi and NCEES) and identify any remaining weaknesses. I also did a bunch of the PPi Six Minute and Structural Engineering Solved problems.
3. I felt the best part of the course is that you end up with a binder full of notes and solved example problems, which I referenced several times during the actual exam, and you should end up feeling comfortable with all the specifications. Not all the material was completely relevant, as a bridge guy I dozed off during the detailed depth reviews of NDS, ACI, AISC, and masonry, but each class starts off with general review of each specification and was more than sufficient to handle the morning multiple choice problems as I felt confident I could quickly look up the relevant code section(s). I thought their bridge depth review was very good, so I would imagine the building depth reviews would be similar. They also cover very, very basic stuff too (RC beam design, elementary statics, dead load computations, etc) that was not an effective use of my time.
4. Also helped that I had some more "skin in the game". The exam is already tough enough on the wallet with all the references and review materials you need to buy, and knowing that if I failed I'd be out the course fee gave me a little extra motivation. They offer a free retake of the class if you attend all the sessions, so there was a little bit of a safety net.
Hope this helps!
