I am failing to download the attached PDFs. There is no active link attached.

Hi everyone! Thanks for reaching out! The Python course has only one *.pdf file. It contains the Course Notes and it can be downloaded from the Introduction to Python - Course Notes lecture from the first section of the course If you are referring to other *.pdf files/links, please support your question with more specific information (and e.g. with a screenshot), so that we can look into this problem in more detail. Regarding the Time Series Analysis course - I've referred your question to those colleagues of mine that can soon help with an answer. Hope this helps.Best,Martin
