Today we will try to develop test questions.

##### We need access to Python edit

- Available on most campus computers (including our little lab laptops)
- See also https://www.python.org/downloads/ is you want to download one on your laptop

##### Next we need to get Python files to improve edit

Start here:

https://bitbucket.org/Guy_vandegrift/qbwiki/wiki/Home

- From the aforementioned wiki Click Source to get to:
- Source Look in OSUP-1-5-unfinished to get chapter 5 questions. We begin with problem 33 at:
- up1-5-33 Use the 3 dots and open raw to get to:
- a python file you can save

##### Latex edit

If you have Windows and are willing to waste a lot of time download Miktex at: https://miktex.org/. But it is far simpler to upload the question only (after deleting the \ifkey footnote):

- https://latexbase.com seems to work, at least for now.
- I have no experience with https://www.overleaf.com/user/subscription/plans
