Thank you for the course! It speaks for itself that I felt motivated to proceed to the end, even though it was hard going in a few places, e. g. not being very proficient in pandas and seaborn.
If I could make a suggestion it would be to somehow keep a reference handy. I very often had to flip back to previous lectures and notebooks to remind myself of some obscure piece of syntax.
We are glad that you found the motivation to finish 
We do have some handy references in the Course presentation: prerequisites section, but we are also working on each iteration of the course to make it less focused on coding skills and more on ML intuitions.
