“We are confident that this will significantly help you pass your exam. All the best!”

Note: The AWS Database-Specialty Certification exams have a passing score of 750 on a scale of 1000 which is similar to 75%, but I highly encourage you to repeat taking these sets again and again until you consistently reach a score of 95% or higher on each exam. Also I would recommend completing all 4 tests. This approach guarantees a good score in the exam.
