MIT's combined catalogue of courses, programs and open learning materials across every department, with a filter for the free ones and for those offering certificates.
Why I recommend it: Use the "Free" filter first — there is an enormous amount of MIT teaching material at no cost, including full lecture notes and video.
Search engine for free and low-cost online courses and certificates across every major platform.
Why I recommend it: Use this to price-check any class before you buy. Search the skill you saw repeated in job postings and start with the free option.
Full professional certificate covering planning, execution, risk, Agile, and Scrum, built for entry-level PM and coordinator roles.
Why I recommend it: A strong pivot path if you already coordinate work informally. Audit it free, and treat the capstone artifacts as portfolio pieces you can show in interviews.
Entry-level IT certificate covering troubleshooting, networking, operating systems, security, and customer support.
Why I recommend it: Still one of the most reliable no-degree entry points into tech. Pair it with a help desk or apprenticeship application while you study.
Certificate covering security frameworks, threat detection, Python for security tasks, SIEM tools, and incident response.
Why I recommend it: A credible on-ramp into security work. Combine it with a free conference or local meetup, because in this field who you talk to opens as many doors as what you studied.
Certificate covering research, wireframing, prototyping in Figma, and building three portfolio projects.
Why I recommend it: In UX the portfolio is the resume. The reason to take this one is the three case studies you finish with, so treat them as real work, not homework.
Certificate covering spreadsheets, SQL, R, Tableau, and the full analysis process from cleaning to presenting.
Why I recommend it: The analysis habits transfer to almost any role. Even if you never take an analyst title, being the person who can read the data changes what work you get handed.
Coursera catalog of software development courses and certificates, many auditable at no cost.
Why I recommend it: Use audit mode to learn free and only pay if you need the certificate. Pick one track and finish it — a completed project beats five half-done courses.
