I bought three books from here and this one was supposed to be my supplement to the FE Review Manual to prepare for the discipline specific portion (electrical and computer engineering). It turns out I bought the wrong book because there is a discipline specific book. Unless you are really struggling with the electrical and computer engineering non-discipline specific portions, I would not recommend getting this book, especially if you already bought the FE Review Manual. I ended up going through the entire book anyways. It was during the exam that I realized this book did not prepare me for my discipline specific portion of the exam. Regardless, I had plenty of time during the exam to figure out my discipline specific portion questions. In the end, I passed the exam.
Just make sure you get the discipline specific book if that is what you are really seeking. (Posted on 12/9/2014)
