The AWS Machine Learning specialty exam is definitely not an easy exam and you need to be very prepared to pass the exam. Even if you have taken and completed several courses aimed at passing the exam it will not completely prepare you for the kind of questions they will ask you at the exam. I have recently taken the last exam and passed it with a score of 90 % and have already taken and passed several other certificates. I have tried to prepare two practice exams based on my experience from the exam. I made sure that the distribution of questions is similar to what you can expect from the real exam and I have prepared the questions to be scenario-based. If you complete the two practice exams you will be much better prepared for the kind of questions they will ask you at the exam. The AWS Machine Learning is one of the hardest AWS certificates to obtain but it is not impossible if you are very well prepared for the kind of questions you will be asked in the exam. Its a very good certificate to have as it covers two of the hottest topics in IT - machine learning and cloud computing. This certificate proves that you are are able to complete a full machine learning project on the AWS platform - from ingesting the data and doing feature engineering to picking and training the models to deploying the models so it can easily used from outside the platform.
