Hey-o TARDIS Guide! I have been, like many on this site, trying to increase my number of ‘completed’ stories by any means necessary. After nearly a year of struggling to get from ‘7’ to ‘8’ %, I have uncovered a treasure trove of stories that are very quick to complete, meaning that they can get you up to that next percent in no time! In only about a week, I’m going from 8% to 9%! So, without further ado, in no particular order, here’s 
Theta’s guide to inflating your number of ‘completed’ stories fast
Video
- Doctor Who: Lockdown, which was a project launched by Emily Cook during lockdown to keep people social and hopeful through Doctor Who content. It included a lot of short videos.
- Jack and River’s Monster Files, Yaz’s Case Files, Strax’s field reports, and TARDIS index files, series of video ‘files’ on Doctor Who monsters/episodes, a couple minutes long each. Many of these are still available on BBC iPlayer, or the official Doctor Who YouTube channel.
- PROBE case files. I have not heard good things about these and am a little scared to start them but there are a lot of them so, if you’ve already done the classic era of PROBE, it can’t hurt to do these too. Well, can’t hurt… much…
- Collection trailers, which are mixed in on the Guide with the other minisodes. Most Collections of a doctor who series included an extra minisode, posted for free on the official Doctor Who YouTube!
- TARDISodes, very short videos that promoted s2 episodes of doccy who. Some absolute legend remastered them in HD so they’re actually watchable. There are lots of other minisodes that will boost your numbers too - just scroll through the minisodes set to find ones that catch your eye. Relatedly, see TARDIS Cams, only a minute or so each.
- Tales of the TARDIS, which essentially are edited classic episodes wrapped in new minisodes. The minisodes are quick to watch, though there aren’t all that many ToTT, so I’m not sure how far it’ll boost your score. These are on iPlayer.
Prose
- Dr. Men, a series of Doctor Who ‘Mr. Men’ books! These are 32 pages each, but for children, so with very little text. It takes about five minutes to read each book. Everyone must go meet Walter the Worm… Experience The Truth…
- The Noodle Incident, an anthology of noodly vignettes, each only a couple pages long. The anthology is free! I do feel obliged to mention that I wrote a story for this and so may be a tad biased, but it is actually the single best thing to ever happen to the Whoniverse and y’all should totally read it. Because each story is so short, it’s an easy way to boost your story number! The same applies to Our Own Voices, another April Fools anthology that you can read for free here, and ‘A Christmas Codex’, a free Christmas anthology! Arcbeatle does a lot of these free anthology type things (:
- School Children is a free Lucy Wilson anthology, written by school kids, available for free! Each story is only a page or two! Suggested by @AlfieSigma . There are a lot of other free short Lucy Wilson stories, too! Though, looks like those are the only ones quite that short.
- The Big Finish short trips (prose) are relatively short - look to be about 10-15 pages each. These replace the original BBC series of short trip anthologies, most of which weren’t nearly as short!
- The Blogs of Doom, short DWM entries a page long. There are a lot of these, so it’s easy to use these to boost your story number, although I find it difficult to get through many of them in a row.
- Brief Encounters, 1-2 page stories from the DWMs, suggested by @nyssaoftraken !
- The Spiral Politic Database, a collection of features on the Faction Paradox website.
- Into the Unknown, which is unofrtunately only available through the internet archive as the website went down. It was an in-universe website made to promote the video game, The Lonely Assassins.
Comics
- Free Comic Book Day comics, as well as the Doctor Who Adventures comics, aren’t quite as quick to read as some of the other stories here, but they aren’t all that long either, and are good fun! In some of the Doctor Who Adventures Magazines, there were also single-page comics called ‘Alien Babies’, suggested by @AlfieSigma !
- The TV Comics are usually quite short, and there are a lot of them, so, easy to boost your numbers! There’s also Battles in Time, another range of short comics. These were suggested by @RandomJoke !
- Give-a-show Projectors are short comic type things, literally four panels each.
- The Radio Times comics are pretty short - suggested by @spaghetti
Audio
- The Big Finish short trips (audio) tend to be quite short - stories form volume 1 have an average of less than 20 mins each! Suggestion from @DoctorWhoTR
If you have any suggestions, please reply and I’ll add them to the list!
