This summer I decided to get serious with doing the Google Certified Educator Level 1 exam. I started with a plan of study, tried out all the required skills and finally registered for the 3-hour exam. It was tough but I passed at the end. A good tip for success is to try to answer all of the questions. If you get stuck, mark that particular question and keep going. At the end, you can come back to it if you have time.
