I don't think the practice tests will ever be "just" like the real test. I believe the purpose of the practice tests are to get you familiar with your reference material and point out your areas of need. I took the April test and just missed passing and I did great on the practice tests(85% avg), but was unable to study the last month due to other issues. I didn't tab my books very well and I had a binder that had some information in it, but I wasn't really quick at locating what I needed. This time, I took the same tests(spin up, CI and NCEES) but my focus was different. I tabbed my books as I tested and more importantly wrote out the reoccuring formulas and information in my binder as I graded my test. I hammered the practice tests every night, scored a little better (90-95%), but more importantly, I was faster at getting to the information. I honestly thought the test last week was pretty straight forward and I finished in about 2-2.5 hours each session, double checked my work and turned in the test morning and afternoon with about 30-45 min to spare.
