We do have a few questions from recent exams in our pool, but it cant be emphasized enough that when taking the practice test, its important to focus on the subject matter rather than the actual question and answer. The practice test shows you which areas you need to study up on.
Many of the questions in the bank are official questions that have since been removed from NETA's pool. That doesn't mean that the material is irrelevant, they have just changed the wording and maybe added a few variables. If you know the theory behind what you are being asked it doesn't matter what the question is.
If you are frequently missing questions about confined space, for example, don't just try to find the right answer and remember it but instead study up on the appropriate standards. There are many links contained in the study guides to help you get started.
Its been said that the new Level 2 is as hard as the old Level 3 was. We have made our practice tests harder as well by moving some old level 3 questions to the level 2 but it would be a good idea to try your hand at a level 3 practice test just to see how you do and give you an idea of what you could be up against.
Bottom line is don't expect to pass your test only by taking practice exams. Study your missed questions and discuss them with your co-workers and the TestGuy community. Be sure to share any tips you may have for future test takers that visit the site.
Best of luck to you!
