Nothing beats rolling up your sleeves, tabbing the heck out of your textbooks, and learning the material yourself. Unless the course is weeks long (like many BAR exam prep courses) I'm willing to bet it's gonna be worthless. The SE exam is so broad yet detailed, and a daylong course is only gonna give you a wide swath of what will be on the exam....you can do that yourself by looking on the NCEES website where it outlines what subjects are on the test.
Your money will be better spent on good reference materials. Definitely get the NCEES practice test, and maybe the 6 minute problems book. Get a good analysis book, I recommend the one by Leet, and learn all your basics. Concrete book by MacGregor. Wood book by Breyer. Steel book by Salmon, and any masonry design guide should do
I found the Structural engineering reference manual to be worthless.
The 246 practice problems book was also worthless.
There's a lot of material out there that will waste your money, so beware. Every book I bought authored by Williams or Buckner was garbage. PPI2PASS pushes a lot of material that looks good on their website, but when in reality are poor-at-best references for the actual exam.
Once you get through the SE1, the SE2 will be cake. Good luck!
