I am one of the older "wiser" (haha) LSAT takers and I started studying full time in October. I have been out of college for 30 years (yeah you read that right)... My goal was to score in the low 160's to get into my state law school that has great social justice / legal aid clinics and is the most affordable for me (I will have 2 kids in college in September!).
I was progressing steadily but then hit some crazy inconsistent scores in May with some of the later PT'S after hitting the low 160's a few times. I was slightly panicked and did not know what to expect sitting for June, but I managed to keep my wits about me and go in fairly focused. I did not hit my goal (just under) but kept the score to be sent with my super late application for this fall. Well, not only did I get in but with a hefty and totally unexpected merit scholarship. SO! All this to say a hearty thanks to 7 Sage - the curriculum is the best out there and the community is really an invaluable part of beating the head game that makes the LSAT such a brutal experience. And to those of you not shooting for a 170 or a T-14 school, keep at it and don't get discouraged when it all feels overwhelming and impossible. If I can do it, you definitely can do it. Shout out to the old-timers who like me are starting in September, good luck!
I use Headspace (premium) regularly and I really like it. I had been meditating prior to the LSAT studying but not consistently. I meditate daily now, just 15 minutes or so and sometimes again in the evening if I am having trouble sleeping. I find Headspace has a lot of options, you can meditate with a lot of guidance or a lot of silence, depending on what you feel like. I also just tried the Calm app but I don't like it as much. I think with meditation, it can be a lot about "fit" and whether you just simply like the person's voice or not! :)
Meditating has most definitely helped me with test-taking in that it allows you to more readily not identify with your thoughts, to "see" your thoughts, for lack of a better word. I have tremendous text anxiety, even when just taking PT's in my home office and it has helped a lot with that.
My other de-stress techniques are getting myself out for a hike with my pups and just exercise in general. Another decent meditation app is Insight Timer. I just use the free version and mainly without a guided mediation, just for the timer and some bells at different intervals, though they have some great guided meditations too.
Best of luck --
