Hello everyone.
First of all, thank you so much for compiling this amazing Data Science curriculum!
Apologies if this has been mentioned before, but I'd like to point out that Coursera has recently removed the ability to audit courses for free (without a certificate) and added preview mode, which allows a non-paying user to only access the first module.
I've found replacements for 2 of the courses:
Tools for Data Science
Data Science Methodology
These can be accessed on EdX for free:
Data Science Tools
IBM: The Data Science Method
The first one is the exact same course, the second one I need to confirm as I haven't started it yet. I hope this helps.
Thanks again for all your work!
