I've been doing a lot of transportation problems lately from various sources (Goswami, NCEES transpo book, Testmasters, and 6 min solutions). The degree of difficulty varies. NCEES and Goswami are reasonable while Testmasters and 6 min solutions can get tough and confusing. If the problems are like NCEES and Goswami then I'm very confident. If they are like the hard 6 min solution problems then not so sure. I guess for the people who have taken it, is the ncees sample problems a good representation on the types of questions on the test?
