SAID ARIYANDI

As a medical records professional, I found Harvard's CS50x 2026 to be an incredibly eye-opening experience. While the course covers broad computer science fundamentals, the logical thinking, algorithmic approach, and understanding of how data structures work are directly applicable to my daily work with Electronic Health Records (EHR) and clinical database management. The course is well-structured and taught in a way that makes complex technical concepts accessible even to those without a background in IT. Highly recommended for any healthcare professional looking to bridge the gap between clinical documentation and data-driven insights.

Harvard CS50 is an outstanding introductory computer science course. The instructor explains concepts clearly, and the course covers programming, algorithms, data structures, web development, and problem-solving. The assignments are challenging but rewarding. I gained a strong foundation in computer science and improved my coding skills significantly. Highly recommended for beginners and anyone interested in learning computer science.
