Can we still take the sample test after 3:10?
(Yes)

Will we have to print out our exam or can we just turn in our solutions on
separate pieces of paper?
(Either option is fine)

Is the sample exam just to show you what the house rules will be?
(Yes -- and to practice uploading and/or converting to PDF)

We don't need to submit it?
(Correct)

I tried editing a screenshot of the sample test, but Gradescope doesn't allow
  for image files
Isn't there an option for "submit images" next to  "submit pdf"?
There is, doesn't have an option for upload (at least on my computer)
Oh youre right, that link doesn't lead anywhere
(I believe you can upload images for each problem, OR a single pdf)

If you have an iPhone the notes app will turn pictures into pdfs for you

will Maxwell equations be on the midterm?
(No)

(Good list of topics:)
hodge
duality
exterior derivative
Properties of d
minkowski vs euclidean spaces
Pictures of forms
signature
*(a^*b)
dr vector and finding orthonormal bases. Finding vector calculus derivatives
  in the language of differential forms.
stacks

We don't get docked for not using Einstein notation do we?
(Correct.)

Is the missing part the "bar" notation? (ie. d bar, star bar, alpha bar, etc.)
(No; this won't be on the exam)

Will we need to justify steps with info from the book
But since it's closed book we don't need to cite as specifically as on the hw?
(No need to cite the text, but do include enough that I can follow your
  reasoning)

You may have already answered this, but if we mix up the Einstein notation is
that dockable?
Such as putting the subscript where superscript should be
(No)
