Query: Great study aid

This book was written very well and is exactly what you need to pass the BCRAN certification exam. I used it to help with my studies and passed the test the day after the cisco course ended. I read it from cover to cover 2x and went back through it after the exam and found about 80% of the stuff from the test in this book. Highly recommended.
