Welcome to "Comprehensive Machine Learning Practice Test: Skill Mastery."

This course is all about testing what you already know about machine learning. It's divided into four main sections, each focusing on a different part of machine learning.

Section 1: Foundations and Introduction to Machine Learning

Test your basic knowledge of machine learning concepts and terms. This section is perfect for making sure you understand the fundamentals.

Section 2: Data Preparation and Feature Engineering

Here, you'll tackle questions on preparing and cleaning data, and creating features for machine learning models. Expect both coding and theory questions to test your practical skills.

Section 3: Core Machine Learning Algorithms and Model Evaluation

This section covers the algorithms used in machine learning and how to evaluate their performance. You'll face coding questions on implementing these algorithms and theoretical questions on evaluating models.

Section 4: Practical Implementation, Ethics, and Tools

Focus on the practical side of machine learning, including real-world applications, ethical issues, and the tools you’ll use. This section has a mix of coding and non-coding questions.

By the end of this practice test, you'll have a solid idea of your strengths and areas to improve in machine learning. This isn't about learning new things—it's about testing what you know.
