Dataquest is an effective learning platform for data science beginners, and it consistently ranks in the top five of all courses on my best data science course page.

Their platform is like an interactive textbook, where you'll read a lesson and solve problems using Python right in your browser.

For more details about their platform, see my review of Dataquest.

DataCamp is a data science platform like Dataquest but teaches more through video instead of text. For a better comparison, see Dataquest vs DataCamp.

Overall, DataCamp is a good value for the amount of content since there are short video courses on tons of foundational data science skills.

Udemy's deal effectively makes most courses on the platform only $9.99, their lowest price.

Udemy courses are the most practical for picking up new programming languages, technologies, and tools, whereas Coursera and edX courses are better for learning theory.

Udemy seems to have the most courses of any platform, so I can't list all of their best options– the ones above are some of the best courses I've personally experienced.

• The deal: Use code to save 20%
• Dates active: November 15–29, 2024
• Best courses:
  • Statistics and Data Science MicroMasters — MIT
  • Computer Science for Artificial Intelligence Professional Certificate — Harvard
  • Big Data Analytics Using Spark — University of California San Diego
  • Learning Python for Data Science Professional Certificate — Harvard

If you've taken some college-level math, edX programs could be a better fit since they're usually more rigorous than other platforms.

Edx courses are offered less frequently than Coursera, but the content is top-tier—some of my best online learning experiences were through edX courses.

Unfortunately, edX doesn't have a sitewide subscription plan like Coursera Plus, but with this BFCM deal you get the best price of the year.

• The deal: Use code to save 50% on Pro subscription
• Dates active: November 21 to December 28, 2024
• Best courses:
  • Machine Learning/AI Engineer Career Path
  • Data Engineer Career Path
  • Data Scientist: Natural Language Processing Specialist
  • Learn Python 3
  • Learn the Command Line

While primarily known for its highly-rated Python course, Codecademy has expanded its offerings to include many excellent data science courses.

Codecademy is similar to Dataquest in that it's a text-based, interactive platform for learning in your browser. Both platforms have free trials, so you can evaluate both to see which you prefer.

• The deal: 50% off sitewide with code
• Dates active: November 21–28, 2024
• Best courses:
  • Data Scientist Nanodegree
  • Artificial Intelligence Nanodegree
  • Self-Driving Car Engineer Nanodegree

Udacity's Nanodegrees are more expensive than most other options on this list—the prominent instructors, mentorship, projects, and career resources are all factors that contribute to Udacity's higher price.

Joining one now with the current discount is most likely your cheapest entry point for the entire year.

• The deal: 50% off annual subscription
• Dates active: November 25-30, 2024
• Best courses:
  • Complete Python Mastery
  • Complete SQL Mastery
  • The Ultimate Docker Course
  • The Ultimate Git Mastery Course

CodeWithMosh is a full-featured academy with hundreds of videos and exercises for each topic.

In my SQL course rankings, their SQL course is one of the best for learning MySQL from a beginner to an advanced level.

With this deal, you'll get access to all courses on their platform, making it an excellent price-to-value ratio for learning core software engineering sk Python, SQL, Docker, and Git.

You can't go wrong with any course or platform listed above. Dataquest, Coursera, and Codecademy offer the best value for whole platform subscriptions, but Udemy and edX have deep discounts on world-class individual courses.

If I missed a good course or platform, let me know in the comments, and I'll add it to the list.
