<p>A computer science roadmap leveraging completely free resources from major institutions like Harvard, Google, and IBM moves from standard programming foundations up to advanced machine learning tracks.</p> <p>You can access these elite materials at zero cost by utilizing the &#34;Free Audit&#34; track on platforms like edX or by applying for Financial Aid on platforms like Coursera.</p> <p>Step 1: Core Computer Science Foundations (Months 1-3) Before choosing an industry specialization, build your problem-solving, logic, and fundamental programming skills.</p> <p>The Course: Harvard&#39;s CS50x: Introduction to Computer Science via edX. What you learn: C, Python, SQL, data structures, and algorithmic logic. How to get it free: Select the &#34;Audit this course&#34; option during registration to access all assignments, lectures, and materials for $0. (Note: If you submit work directly through CS50&#39;s internal grader tool rather than edX, Harvard even issues a free certificate of completion).</p> <p>Step 2: Advanced Language Proficiency (Month 4) Deepen your command of a single programming language needed for specialized work.</p> <p>The Course: Harvard&#39;s CS50P: Introduction to Programming with Python via edX. What you learn: Functional programming, regular expressions, file I/O, and testing using Python libraries. How to get it free: Use the Free Audit track on edX.</p> <p>Step 3: Pick an Industry Specialization (Months 5-9) Choose one distinct pathway aligned with your long-term career goals. Path A: Data Science &amp; AI/ML The Course: IBM Data Science Professional Certificate via Coursera. How to get it free: Click the &#34;Financial Aid Available&#34; link next to the enroll button on Coursera. You will need to submit a short text explanation; applications are standardly approved within 14 days. Path B: IT, Networking, &amp; Cybersecurity - Google Cybersecurity Professional Certificate via Coursera. Path C: Software Engineering &amp; Web Development - IBM Full Stack Software Developer Certificate via Coursera.</p> <p>Step 4: System Architecture &amp; Cloud (Months 10-11) Top tech employers prioritize developers who know how to scale applications using modern infrastructure.</p> <p>Step 5: Portfolio Creation &amp; Interview Prep (Month 12) Consolidate your knowledge into functional code and prepare to pass tech screens. Build three complex repositories and upload them to Git. Practice daily on HackerRank or LeetCode.</p>
