COACH NEEDED: Google ADWORDS Professional Exam

Hello, I'm looking for a tutor. I'd like to try to obtain the: **Google Adwords Qualified Individual** certification but I'm a little unsure of the structure and content of the exam. The way Google puts it - "Just read through our stuff" doesn't inspire much confidence. I don't want to write the exam multiple times just to figure out what's important. I don't want to waste time studying stuff that they don't ask questions about. Can anyone who ALREADY has the certification help me with advice, tips, etc... so that I can focus on what is important and write the exam within the next couple of weeks / month and have a much higher degree of confidence of passing? Thank you
