I just came across an awesome site that provides great tutorials on how to master Google Adwords.

Put the credit card away, it's totally free! No upsells .. No back end stuff ..totally Free.
The tutorials are excellent. Plenty of content and easy to understand.

It also has a forum where you can post questions to and get help with campaigns.

Not to mention the free keyword research tool that you can use too. This was pretty darn good. I used it last night for one of my campaigns.

Check it out:
