Reference Materials

Blog

Jayendra’s Blog

This was an excellent resource for understanding the exam topics. The content is well-organized, and I recommend following this guide from start to finish on your learning path.

Books

Introduction to Machine Learning with Python: A Guide for Data Scientists

I read this book as a beginner’s guide for machine learning.

AWS Official Documentation

Practice Tests

Whizlabs - AWS Certified Machine Learning - Specialty

I used this for my preparation.

Udemy - AWS Certified Machine Learning Specialty: Full Practice Exam

I did not use this, but it has a high rating and may be better organized than Whizlabs.

Conclusion

Frankly speaking, I think that passing this exam alone cannot guarantee that you are a specialist in the machine learning area. However, the exam offers a great opportunity to learn machine learning with AWS.
