The NCEES practice tests for transportation were almost completely worthless. I actually feel that me taking the NCEES practice test on Thursday (got 70 of 80 correct) did nothing more than waste 8 hours that could have gone to much better use just reviewing my notes or something.The AM went smoothly. I found the PM Transportation Exam to be heavy on traffic and conceptual based. I can only hope. This was my first time taking the exam, but I can say it was NOTHING like the PE Practice Exams put out by NCEES or anyone else!
I don't think the test maker (NCEES) should be selling "practice" tests at all now that I think about.
If the material were too similar then it provides too much help and may not show your actual knowledge/ability. But the complete lack of corresponding concepts, except for the few guaranteed geometry problems, the practice tests are just misleading.
The problem is, Ncees knows what's on the test, so they probably specifically do not include anything "similar" on the practice tests. At least with other publishers, they are actually trying to make practice tests that will represent the real test.
