Title: How to Pass the MLS-C01 Exam: Study Tips, Domains, and Practice Resources
In today's digital world, the use of machine learning (ML) has evolved from niche research projects to mainstream business solutions. Organizations across industries rely on ML to enhance decision-making, automate processes, and improve customer experiences. As a result, there is a growing demand for professionals who not only understand machine learning but can also implement it on cloud platforms like Amazon Web Services (AWS).
The AWS Certified Machine Learning – Specialty (MLS-C01) certification is designed to validate your ability to design, build, deploy, and maintain machine learning solutions using AWS.
What is the MLS-C01 Certification?The MLS-C01 certification is one of AWS's Specialty-level certifications, focused on machine learning. It tests a candidate’s ability to design and implement ML solutions using AWS technologies and best practices. It’s an advanced certification, so candidates are expected to have a strong foundation in ML concepts and real-world AWS experience.
It’s particularly suitable for roles like:

Machine Learning Engineers
Data Scientists
AI Engineers
Cloud Developers
Software Engineers working with ML workloads

Why Earn the MLS-C01 Certification?Earning the MLS-C01 credential offers multiple benefits:

Career Advancement: Certifications like MLS-C01 are often a differentiator in job applications and promotions.
Increased Salary Potential: AWS-certified professionals typically earn higher-than-average salaries.
Credibility: Demonstrates verified ML skills on AWS, including modeling, automation, and deployment.
Access to Opportunities: Makes you a more competitive candidate for cloud-native ML roles.
Validation of Skills: Shows that you not only understand ML concepts but can apply them using AWS tools and infrastructure.

Exam OverviewHere are the key facts about the MLS-C01 exam:

Exam Code: MLS-C01
Format: Multiple-choice and multiple-response questions
Duration: 170 minutes
Cost: $300 USD
Delivery: Online proctored or at a testing center
Languages: Available in English, Japanese, Korean, and Simplified Chinese
Recommended Experience: 1–2 years of ML experience and deep AWS knowledge

Although AWS does not publish a specific passing score, industry feedback suggests it's around 70–75%.
Domains Covered in the ExamThe exam is divided into four primary domains. Each domain tests different aspects of your knowledge and skills.
1. Data Engineering (20%)This domain focuses on gathering, cleaning, transforming, and storing data for machine learning purposes.
Key skills:

Ingesting data from multiple sources (structured, semi-structured, unstructured)
Using AWS Glue, Kinesis, Data Pipeline, and AWS Lambda
Data normalization and transformation
Secure and scalable data storage with Amazon S3 and Redshift
Handling data quality issues, missing values, and inconsistencies

2. Exploratory Data Analysis (24%)This domain assesses your ability to analyze and understand data before modeling.
Key skills:

Feature engineering and selection
Detecting outliers, correlations, and biases
Dimensionality reduction (e.g., PCA)
Visualizing data using tools such as Amazon SageMaker and Matplotlib
Identifying data distribution issues and skew

3. Modeling (36%)This is the most important domain in terms of weight. It assesses your ability to choose, train, evaluate, and optimize ML models.
Key skills:

Selecting the appropriate ML algorithm for a given task (e.g., classification, regression)
Model training and evaluation
Metrics such as AUC, ROC, precision, recall, F1-score
Hyperparameter tuning with SageMaker
Using built-in SageMaker algorithms and custom containers
Working with imbalanced datasets
Automating model selection with SageMaker Autopilot

4. Machine Learning Implementation and Operations (20%)This domain tests your ability to deploy and monitor ML models in production environments.
Key skills:

Model deployment using Amazon SageMaker endpoints
Batch vs. real-time inference
A/B testing, blue/green deployments
Monitoring models for performance and drift
Logging and alerting with Amazon CloudWatch and Model Monitor
Managing retraining and version control

Key AWS Services to KnowFor the MLS-C01 exam, you must have hands-on familiarity with these AWS services:

Amazon SageMaker – Model building, training, tuning, and deployment
Amazon S3 – Data storage
AWS Glue – ETL for data transformation
Amazon Kinesis – Streaming data ingestion
Amazon Redshift / RDS / DynamoDB – Database options for structured data
Amazon CloudWatch – Monitoring and logging
AWS Lambda – Running inference and triggering workflows
AWS Step Functions – Orchestrating ML pipelines
IAM – Permissions and access management for ML workflows

PrerequisitesAlthough there are no formal prerequisites, AWS recommends:

At least one to two years of hands-on experience in ML or data science
A strong understanding of AWS cloud services
Proficiency in Python and relevant ML frameworks (e.g., Scikit-learn, TensorFlow, PyTorch)
Familiarity with SageMaker and data pipeline automation

Study ResourcesTo prepare for the MLS-C01 exam, use a mix of study materials:
1. AWS Official Resources

AWS Skill Builder learning plans
Hands-on labs on Amazon SageMaker and related services

2. Online Courses

Udemy: AWS Certified Machine Learning Specialty 2024 – Hands-On Course
Coursera: Machine Learning with AWS Specialization
A Cloud Guru / Pluralsight: MLS-C01-specific prep courses

3. Books

"AWS Certified Machine Learning Specialty: MLS-C01 Certification Guide" by Somanath Nanda
"Data Science on AWS" by Chris Fregly and Antje Barth

4. Practice Tests

Whizlabs
Tutorial Dojo
Practice exams in Skill Builder

These platforms provide realistic practice questions that mimic the difficulty and format of the actual exam.
Study Tips and StrategyPreparing for the MLS-C01 exam can be overwhelming without a strategy. Here's how to approach it:
Set a SchedulePlan a study schedule over 6–8 weeks. Aim to study at least 10 hours per week, allocating time for reading, labs, and practice exams.
Learn by DoingSet up a free AWS account and experiment with:

Creating SageMaker notebooks
Running ML models
Deploying endpoints
Automating pipelines with Step Functions
Monitoring models with Model Monitor

Focus on High-Weight DomainsSince Modeling and EDA together account for 60% of the exam, prioritize these topics. Practice data preprocessing, model selection, and evaluation techniques.
Track Your ProgressUse checklists to track which domains and services you’ve covered. Identify weak areas and revisit them regularly.
Practice, Practice, PracticeTake at least 3–4 full-length practice exams before attempting the real one. Simulate test conditions and review your incorrect answers carefully.
Common Mistakes to Avoid

Ignoring AWS Tools: Knowing ML theory isn’t enough. You must understand how to apply that theory using AWS services.
Neglecting Data Engineering: Many candidates overlook data ingestion and transformation—20% of your score depends on it.
Overfocusing on Theory: Don't spend all your time on algorithms. You also need to know how to deploy and monitor models in production.
Rushing Practice Exams: Take your time to review and learn from your mistakes in practice tests.

On Exam DayHere’s what to keep in mind on the day of your test:

Arrive early if testing at a center or log in 30 minutes early for online proctoring.
Have a government-issued photo ID ready.
Read questions carefully—many are scenario-based and can be tricky.
Flag questions you’re unsure about and revisit them if you have time.
Manage your time effectively: roughly 1.5 minutes per question.

What Happens After You Pass?Once you pass the MLS-C01 exam, you’ll receive:

A digital certificate and badge from AWS
Listing in the AWS Certification directory (optional)
Access to exclusive AWS events and communities

You’ll be qualified for roles like:
