Download Jupiter notebook as LaTex (.Tex)

Yes, it is true that as soon as you stop paying or as soon as your Financial Aid stops, you will lose access to the assignments on the website. This is mentioned on the FAQ Thread. It is an excellent idea to save copies so that you can later refer to them. If you do as you described and download as “ipynb” and then convert those to PDF or TeX you should be covered. I would recommend saving both formats. As I mentioned, the “ipynb” files are actually executable either in your own Jupyter environment or on Google Colab or other such environments. Also note that if you really want to execute the notebooks locally, you’ll need to save copies of all the other files (data files, additional python support routines and so forth).
