    Every year, tens of thousands of people embark towards taking the exam via private study, Cisco Academy courses, or online training. The sad truth is most students quit along the way, and for those few who actually do attempt it, only 50% pass. All that time, effort, and money wasted! If there are so many manuals, CBT courses, lab simulators, exam engines, and study resources out there, then what goes wrong? This is the question Cisco trainer Paul Browning wanted to get to the bottom of. After interviewing thousands of students, he discovered that most people quit because they are simply overwhelmed with the sheer volume of material they need to digest and, of course, the large number of hands-on skills they need to be able to demonstrate in the exam. Add to that the day-to-day stresses of commuting to work, bringing up a family, and the distraction of everyday problems and challenges; it's no wonder people quit. This is where Cisco CCNA in 60 Days can help. Devised by two industry experts and countless Cisco students just like you, the 60-day programme breaks down every exam requirement into a daily study task. All you need to do is open the book at the relevant day (from 1 to 60), read the theory, and complete the lab. Every lesson is reviewed several times in the form of exam questions, review sessions, a handy exam cram guide, and, of course, hands-on labs for you to follow. You can choose to take the CCENT after the first 30 days and the ICND2 after the next 30 days, or you can take the CCNA after 60 days of study. Here is what is included in your study guide: 60 daily study tasks Full explanations of theory Real-world tips and advice Over 47 hands-on labs, plus 15 bonus CCENT and ICND2 labs CCENT and ICND2 cram guides Bonus VLSM guide Motivational goal-setting guide Downloadable videos Author Paul Browning is a former police officer who used his CCNA qualification to help him make a career change to IT.

He is the author of several Cisco study guides. He has also created the online Cisco certification training sites, including www.howtonetwork.net and www.in60days.net.
