I have had similar timing issues.

Okay. You have limited time; and the main issue you are having is on LR. so, I would say...start by figuring out how long different question types take you. (Time yourself NOW. On EACH type of question, going as fast as you can while also being confident in your answer choice)

This will give you a good understanding of your strengths and weaknesses: What can you confidently answer in a way you feel is efficient, and in under 1 min 15 seconds? What can you confidently answer with extra time? What do you still struggle with regardless of time?

Then, you can:

1.) Focus on studying several (3-5?) high-frequency LR question types that you are reliably getting right with the shortest amount of extra time. (There really isn't enough time to develop complete, confident instant recall understanding of all the question types. So I think it's better to be totally confident on a core group that'll make up the vast majority of questions than trying to do everything.)

2.) Slowly reduce the time you spend on those types of question. You have max 1 minute 15 seconds for each LR question.. Then do bulk sets of 10 questions -- reducing by 5-10 seconds each time until you get to the 1.25 minute point.

3.) On practice tests, and on the test day, definitely SKIP and RETURN to questions that you consistently take longer to answer. (For me, they're the parallel reasoning).

4.) Once you are down to time, pace yourself using an analog watch...(this screwed me over when I went from practicing with my cell phone timer to using a crappy analog watch!)

5.) Think of the test like throwing free throws. For each section, you have 25 free throws in 35 minutes. Stick to pace, each new question is a whole new free throw worth the same number of points. If you think of each individually, then you won't psych yourself out based on any challenges you had on previous sections or questions.

Beyond that...I'm not sure if there really are any fast and dirty shortcuts. Reliably answering questions quickly comes with familiarity with basic core concepts -- (e.g. - It's been 13 years since I took pre-calculus or hard math! Right now, I could answer all the GRE questions quickly...but I'd be re-digging up my knowledge from 13 years ago, and each question would take me 5 minutes; rather than 30 seconds if I intuitively knew the answer); Reliably answering quickly after 4 sections comes with building stamina to stay focused and engaged.

(If your issues were on LG & RC -- I might suggest figuring out if just spending 12.5 minutes on only 3 games/passaged would give a higher score; and then focusing on concepts to make sure you can get 95 or 100% of those right)

Agree with the previous poster. The main thing: there seem to be a number of unknowns regarding what the online test will look like. In particular, what mark-up features (e.g. freeform stylus to annotate web text on RC & LR? Or just highlight sections? And whether pen and paper will be allowed for ALL sections or only logic games.) This will have a big impact on test taking strategy. Report backs from people who did the online test simulations vary. The Official LSAT prep resource on KHAN -- that interface only allows mark-up in RC ONLY, and there only highlighting (not double-underlining, circling, jotting notes).

LSAT will be releasing more information in early 2019, allegedly. So -- I would say until then, practice in paper and online and focus on developing understanding and mastery of key concepts and NOT things that will or could be affected by the print--> digital change. (So creating LG set-up strategies; becoming familiar with the LR question types and typical right and wrong answers; developing a general understanding of things to focus on in RC and common right and wrong answers). This will be useful regardless of the test format and digital functionality. And wait on things like developing specific strategies for marking up RC and LR text.
