Computer Science Fundamentals
Test Preparation
Course Introduction
Computer Science Fundamentals provides an introduction to the core concepts of computer science, including problem-solving techniques, algorithms, data structures, and basic programming principles. This course covers the foundational theories underpinning computer operations, logical reasoning, and computational thinking. Students will explore concepts such as abstraction, recursion, and modularity, gaining practical experience through hands-on programming exercises. By the end of the course, students will have a solid understanding of how computers process and store information, and will be prepared for more advanced study in the computer science field.
