Probably needs to be updated

I took the exam yesterday and received an unofficial 'pass' result. I completed all of the review items in this book and studied my other texts and class notes. At this time, I have mixed feelings about recommending this book. First, the exam content breakdown is not the same as it was when this book was written. Secondly, I found a few obvious errors in this book (in one question the names Enrique and Henry are used interchangeably; the item counts in the scoring categories for the practice exams do not always match the item counts in the grading categories). As I also questioned a couple of the practice item answers, finding other inaccuracies validated my concerns about those items. Admittedly, I seriously questioned only about two out of hundreds of items.
This guide would be more useful if it was updated to reflect the current exam content (and more carefully edited). It would be tremendously improved if the answers to the questions were referenced as they are in the online items available through the NCTRC website. I suspect that some of the questions were taken directly or paraphrased from the TR texts but hunting for the relevant chapter or section is pretty difficult given the number and length of options. Referencing the answers would help me guide my studies and give the material greater credibility.

****UPDATE October 2014****
I just took (and received an unofficial 'pass') the CTRS exam again because I had not accrued ample continuing ed hours while I was attending graduate school for the past 4 years. I used the newest version - 4th edition, copyright 2013 - of this study guide, and I would give this version about a 4.5 star rating. It was a much better match with the current exam, and I think that completing several of the practice exams definitely put me in the right frame of mind. Looks like Amazon is not carrying this edition so I recommend that potential test takers seek out a copy.

Great book- watch out for updated versions before buying though; this is the type of resource that needs constant updating

Calculator is good but needs updated to newest version. I don't know how to do it which is why I gave it 4 stars.

They are still updating it from several problems they have had. Hopefully they will have them all fixed soon. I do not like being required to purchase a new one every couple years. Wish they had an update that could be installed at a discounted fee. This version won't let me back it up on the computer, just on a thumb drive. I don't like that. Their customer service stinks! No way to reach a real person that I can find. Only reason I keep it is because I can do my bookkeeping better than by hand.

I bought this for my daughter and unfortunately I didn't do enough homework. The computer works fine, but it is out of date and some updates are unavailable for it.

Great stuff, but getting dated now.  Teslas are changing very fast both in hardware and software.
Need a website where updates can be posted, or more frequent updates to Amazon digital version (should be relatively easy to do, no?)

Having problems with it already. Either a software issue or hardware. May need to take it in to a professional

Some of the add-on parts used are no longer available (wireless routers) or replaced by newer versions (BlueSmirf). Fundamental approach still applies but will take some reader knowledge to apply with current products. Interesting hack book nonetheless.

I usually love this book, but they apparently don't update it...they just throw a new copyright date on the front of the old text.  The hypertension section is out dated, among others.  This may be okay for some but I hold them to the standard of pushing current information with a clinical context.

Not installed yet but should accomplish what it is intended to do.

Not a terrible book, but quite out of date at this time. (This was our required book for class for the Spring 2017 semester.) There are several links they give that no longer work (aka - a LOT of the links). Also, I have come across several spelling and grammatical errors. Sometimes the terms definitions do not make sense and I have to look it up in the back of the book where it may or may not have been corrected to make sense.

Useful to a point, but could be in larger format with color photography and needs an update. Still useful though.

Not completely updated.  Still missing some roads that had been around for four or five years.  More recent points of interest info.

Can't update it.  I just get an error message that it can't connect to the server.  Can't download the state software because it says the federal needs to be updated first but I can't do that because it can't connect to the server.  I am very frustrated with this.

Just make sure to update Windows 10 first.  I had to plug it in then do a Windows update manually before it was recognized.
