I took testmasters as well and I have to say I was dissapointed.
I really think the only reason I passed this second go round was due to taking in several college textbooks from ENV, Geotech, and even statics.
I am sure those qualitative (definition prooblems) on the the exam were easy if you are in the business, but I couldnt find them in the CERM, but I had borrowed some ENV textbooks that had the answers, and bringing in my old geotech textbook helped this go round.
I even brought a statics book because it had an large amount of truss / beam problems examples worked out.
The dude from testmaster said they set the class up to help you get 30+ in the AM, and then you were on your own in the PM for the most part. But I didnt get any info from the TM book in either the GEO, or ENV section. But the Water and the Transportation sections were the best parts of the class..
I think if you take the transpo afternoon you also have to take the MUTCD, HCM , & Roadside Design Guide.
