Quoting what I mentioned in #228:

> I tried looking into showing Excel sheets in a new tab as opposed to auto-downloading them and it turns out that only PDFs are viewable in the browser, but not Excel sheets and the like. To have them be viewable in the browser, you'll need to upload them to Google Docs/Sheets/Drive and have the user redirect to it. As they are right now, they can't be opened up in a new tab for the users to see; they've got to download them first. But again, PDFs are fine, though.

Aside from that, the new Excel sheets have been uploaded and I've added a pop-up for the Stud Fee Agreement. Please test at your convenience.
