As the IT sector is rapidly advancing, I keep seeing more and more people wanting to start a programming career—but the biggest problem is always the same: where do you begin, especially if you can’t pay for expensive courses. In this video I share what I genuinely think is the best free option in 2024: Harvard’s CS50: Introduction to Computer Science. I leave the official link in the description, and I explain what you’ll actually learn so you can decide if it’s the right starting point for you. I go through the key topics CS50 covers: thinking algorithmically, solving problems efficiently, and core concepts like abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and even web development. You also get exposure to multiple languages—C, Python, SQL, JavaScript, plus HTML and CSS—so you’re not stuck in a single toolset. My main takeaway is that the course is very well structured, and after completing it you’ll have a clear understanding of programming and start to think like a programmer. It’s 11 weeks, includes practical tasks, and ends with a final project—and if you score 30 and complete the final project, you can earn a certificate to strengthen your resume.
