How do you stay focused for the whole LSAT?

[gordonpiper]

For me, the hardest part of the LSAT isn’t just the questions—it’s keeping my brain sharp for the full test. I usually start fine, but by the later sections, my focus drops, and I make careless mistakes.

How do you guys build up your endurance? Do you practice full tests, take breaks in a certain way, or have any tricks with sleep, food, or mindset that help you stay sharp?
