Just want to share that I successfully took the AWS SA Pro exam. It was rough. As Anthony mentions in the prep materials, this course itself - just watching the videos - won't be enough. You have to study the white papers. Read them carefully and take notes. Review the FAQs for Direct Connect, Dynamo DB, RDS, S3/Storage Gateway, CloudFront and Load Balacing. The test is really for AWS pros that have 3+ years experience with infrastructure design and cloud architecture. The questions are tough but if you have hands-on experience and know the topic you can quickly eliminate 2 answers and then work with the remaining ones.
