Top 12 free Data Science crash courses

In this blog, we will have a look at the list of free Data Science crash courses to help you succeed in Data Science


With more and more people entering the field, data science and data engineering are surely amongst the topmost emerging areas of work in the 21st century. Higher salaries, perks, benefits, and demand has made it a field of interest for 1000s of people.  


While a good chunk of students is opting for data science in their undergraduate and graduate programs, there are people who are opting for different Data Science Bootcamps to get started with the field.   


However, enrolling instantly in an expensive undergraduate, master’s, or data science Bootcamp might not be the correct choice for one to go with. An individual would want to explore more within the scope of data science before switching fields or making the final call. Hence, below we present a list of free data science crash courses that an individual can go through before choosing their career path.

If you are completely new to data science or planning to switch your career, our Data Science Practicum Program should be able to help you.   


Likewise, data science is an emerging field. Just a single program or bootcamp cannot help you to excel within the domain of data science, engineering, and analytics. You will have to keep learning and update your skillsets with short courses like Python for Data Science to remain competitive in the job market. This list of free crash courses can help you acquire a number of skills like Power BI, SQL, MLOps, and many others.
