I never played the original Rocksmith, so I can't say what are the improvements on this edition. I'm going to evaluate it as a videogame rather than an "educational tool". The good news is that it's excellent at both. I am fortunate not to have the lag issues in its less-than-ideal setting. I really wanted to give this a 5-star review, but two things prevented me from it. The gameplay and the (yes) controller.

Best pes yet ! No Gillich no lags no bad reaction from player or goal keeper ! Best soccore game 2015 :)

Many errors in the answer key. Every section has a wrong answer. Do not buy!! You will be marking yourself wrong for no reason!

I really studied hard using this book (2 weeks) but my test date was canceled due to a snow storm. I went back to school (18 credits) so had no time to continue my studies. I took my test today after not studying for 3 weeks and the information was still there (even though I wish I had taken a practice test a couple days ago since my time management was really off today). I raised my score from a 150 math and 155 English (practice test 1) to a 155/162 for the actual test today. The things I learned in this book I'm sure will serve me for a lifetime.

extremely content with this device and most certainly delighted with the customer service/tech support- highly recommend this device!!!
