Data science careers need math, coding and the right course. Compare free and paid options on Coursera, Udemy and upGrad to match your budget and goals.

Free and paid courses for different goals

• Getting started with no cost: Getting Started with Python for Data Science on Codecademy takes 7 hours and is free. Free Data Science with Python on freeCodeCamp runs 300 hours and is also free.
• A structured university path: HarvardX: Introduction to Data Science with Python on edX is free and takes 8 weeks. IBM Data Science Professional Certificate on edX is free and takes 80 hours.
• Job-ready fast: Google Data Analytics Professional Certificate on Coursera takes 6 months and includes a certificate. Executive Post Graduate Certificate Programme in Data Science & AI from IIITB on upGrad takes 12 months and offers placement support.
• Deep technical skills: Deep Learning Specialization on Coursera is intermediate, 3 months long and carries a certificate. Machine Learning A-Z on Udemy is 43 hours, all levels and carries a certificate.

What free options do not give you

Free courses such as Getting Started with Python for Data Science and Free Data Science with Python provide solid introductions to Python and core concepts. They include certificates and self-paced study. What they do not give you is structured placement support, mentor feedback or a credential recognised by employers for mid-level roles. Paid programmes such as the upGrad Executive PG Certificate or the Google Data Analytics Professional Certificate add career services and a provider-branded certificate that can appear on a résumé. If your goal is a job change, a paid track with placement assistance is worth the investment. If your goal is to learn the basics before committing money, the free routes are a practical start.
