With lockdowns likely to get extended across many locations in the world and offices remaining shut, many ed-tech platforms are offering some of their data science courses and other learning content for free. While professionals adapt to work from home amid a health crisis and an oncoming recession, using the extra time to upskill themselves has become commonplace.
As these platforms launch new and free resources across an array of disciplines, identifying the right courses can be overwhelming. With many free courses from top universities already explored here, we have sought to update that list and include courses that were made free in the intervening period. With that, here is a list of courses to improve your data science skills:
Great Learning Academy’s Data Visualization Using Tableau
About the course: It is not enough to learn how to read data and extract insights from it — how you explain that analysis to stakeholders is what it ultimately boils down to. Many struggle to break down ideas for non-technical people and explain findings in a manner such that they can use it to make decisions.
Visualisation plays an important role here. After taking this course, learners can create easy-to-read graphs and other visual representations of data. It covers dashboard design, visual analytics, and advanced mapping, and includes video content, as well as three quizzes and one project.

Coursera’s Algorithms series
Through the program ‘Coursera Together’, the platform is offering free online learning as the world goes into lockdown amid Covid-19. Free until July-end, its range of courses on algorithms in collaboration with Princeton University is highly rated. Since knowledge of algorithms is commonly tested in data science interviews, this series will be valuable for aspiring data scientists, as well as professionals seeking to upskill themselves.
Algorithms Part I and Part II
About these courses: Offered by Computer Science professors Robert Sedgewick and Kevin Wayne, this series covers all essential algorithms and data structures. While the first part covers sorting and searching algorithms, the second part focuses on string-processing algorithms, among others. Although all features are available for free, learners will not get certifications on completion of the courses.
