The Google Teacher Center has a course that will walk you through the information needed to pass the Google Certified Educator (GCE) Level 1 exam.
Eric Curts has prepared a list of all the things that may be on the exam. There is a large database of questions, so not everyone will get the same questions or topics.
The last resource for Level 1 are Task cards. Working through those (even if you have to Google "how to do it") are going to be your best practice for the task section of the certification exam.
The Google Teacher Center has a course that will walk you through the information needed to pass the Google Certified Educator (GCE) Level 2 exam.
Eric Curts of www.controlaltachieve.com has another list of all the topics that you may find on the Level 2 certification exam.
There is a Level 2 Task card set that works like the Level 1 Task card set. This is not an exact list of the tasks you may see but they will be similar.

I would love to help you prepare for your trainer application. You will need to be training in order to receive your certification. You can train locally in Quanah. I will be hosting Google trainings throughout the summer that you can attend for professional development credit and document as training hours. You can present portions to others to document training experience. Contact me for more information.
