Tutorials dojo coupon? : AWSCertifications
The Tutorials Dojo Practice Tests are a must have. They were similar in structure and difficulty to questions on the exam and also really help you identify weaknesses in your knowledge and address them. I actually only took 5/6 of them getting scores of 64, 66, 68, 78, 82.
