Ok im not sure exactly what you mean by digital because its a paper exam. but i built mine in a spreadsheet, printed it, used the printed one. best of both.

editing on paper is miserable and editing digitally is instant, so you want the building to be digital. searching a screen under time is slower than a thumb on a tab, so you want the using to be paper. print it once you stop changing it, which for me was about two weeks out.

paper the whole way. i am aware this makes me a caveman

spreadsheet gang. being able to sort by page number at the end and catch everything i had put in the wrong place was worth it on its own

One thing on the print version. Print it at least a week before, not the night before. Mine came out with the columns wrapped in a way that made half of it unreadable and I did not have time to fix it properly.

Whatever you pick just stop researching it. I lost most of a weekend to comparing methods and produced zero index. The method is not the hard part

spent a whole evening on this exact question last week and produced nothing. this thread has saved someone two hours, possibly me
