About this course

Are you looking for a structured way to practice and solidify your understanding of computer science? Developing strong problem-solving skills is the most critical step in learning computing, yet finding the right exercises to practice can be challenging. This text-based course provides a curated collection of computer science tasks designed to build your computational thinking from the ground up. You will transition from understanding basic terminology to solving practical logic, data, and algorithmic problems. What you'll learn: - Understand core computer science terminology, data representation, and binary logic; - Apply algorithmic thinking to break down complex problems into structured steps; - Practice solving practical logic puzzles and control flow exercises; - Learn modern Python-based pseudocode concepts to write clean, readable logic; - Analyze basic data structures, including lists, arrays, and key-value pairs; - Explore foundational security concepts like encryption basics and safe data handling. We begin with essential definitions and theoretical foundations before moving into hands-on text exercises that you can solve at your own pace. Each section offers clear explanations and walkthroughs to help you master the material. This course is designed for absolute beginners, school students, and self-taught learners who want to build a rock-solid foundation in informatics without any prior programming experience.
