Well, I met the minimum spend requirement to take the Google Adwords Professional exam so I decided to get ready to take it as soon as I can fit it in my schedule.   I feel pretty confident in my knowledge of the actual workings of Adwords, but I will need to study some special case scenarios that I wouldn’t normally come across (like what the payment terms are if you’re in another country) and need to review some Google policies and such. 

My biggest challenge is finding time in between my client projects to have a clear head, no interuptions, etc.
