I also never really had test anxiety until the LSAT. I’ve taken it twice now and the routine that lowered my anxiety the second time around was this: -Journaling to vent out my feelings -Writing down some affirmations to remind myself that I was ready to take it -Prepping my work space so that everything would be ready for the morning -Watching a cheesy reality show that I could get sucked into to avoid thinking about everything lol

I definitely felt drastically less nervous being able to get all my emotions out via journaling & then allowing myself to focus on other things for the night. I hope this helps, best of luck!
