I don't suggest completing the secondary by hand unless you have incredibly clean handwriting lol. Last year these documents were editable after download (i.e., you could type into an existing text box), and I haven't accessed them this year, but they still should be, assuming they didn't make any significant changes. Download Adobe Acrobat (free) and open the secondary documents through that application instead of Preview, which I think might be the default on most Macs. I suggest opting in for the free 2-week trial of the premium version that allows you to edit PDFs. If there's any part of the document that can't be edited (this happened a few times last year), simply insert your own text box. The premium version allows you to change the font and text size, which is helpful for a secondary like LSU's where there's not much space to add text. For the questionnaire, just be extremely brief when it comes to the "Service Responsibility" section. Their secondary is basically a condensed version of the primary, so try not to stress because they already have this information! And lastly, whenever a signature is required: print the page, sign it, scan it, then replace the page without the signature using the edit PDF tool. It's so tedious, but it looks a lot cleaner, in my opinion.
