Here in Toluca city, I liked the way people prepare for the MLS-C01 certification exam. They do not leave it on fate. They practice harder to achieve the goal. When i arrived here from Spain, i did the same. I signed up for AWS Certified Machine Learning - Specialty practice quizzes online that requires a nominal fee to be paid and i was good to go. I was surprised at the result when i got it today. Such high score was not possible without practice for me. I would suggest it to everyone around the world.
