Can you guys please recommend me on a good adwords book/course?

Perry Marshall hands down! The best course you can ever find for running Adwords campaigns.

Thank you! He has few products... what should I start with?

there is one course from Gauher Chaudhry. He is a pretty big name in PPC and adwords.

I suggest gauhar chaudhary's pay per click formula 3.0, it's an awesome course there you'll learn not only adwords but almost every ppc platform out there. The most important aspect of ppc is tracking, testing and optimizing, gauhar gives some great tips to optimize your campaigns.

BTW if you have a website where you sell your own product or services then I suggest you straight away give a call to adwords, they'll create your campaigns for free for 1 month and help you learn adwords, that knowledge can be applied to almost all the other ppc systems.

But if you have an affiliate site then don't call them, they don't like affiliate marketers - the people who made google what it is today.

The videos on Google's site are actually really helpful.
