The LSAT demands much, including your ability to use your brain for a long period. The LSAT is a total of 205 minutes of a brain workout, with a mere 10 to 15 minute break in the middle. It's not enough to know the material on the LSAT well -- you also must be able to do it well for a long time. To help build this endurance, consider the following:
Do all LSAT study under LSAT timing restrictions
A good way to get used to the 205-minute LSAT strain is to regularly go through it. So, do all of your LSAT study in 35 -minute sections, five sections straight, with a single break between the third and fourth periods. Many test-takers only follow these timing restrictions when they take practice tests. However, you can help build your mental endurance by also doing the same time restrictions when you work on specific question types, review the practice tests that you have taken, or any other LSAT study. If your schedule is tight and you are only able study about an hour per day, you should still break your study time into 35-minute sections that are completely without distraction.
Breathe deeply and regularly while doing LSAT study
When people get tense, they often tighten up their chests and breathe shallowly. Clearly this is bad for your mental endurance. So, get in the habit of breathing deeply while doing LSAT practice. By doing this regularly you will eventually start doing it without consciously thinking about it, and by the time you take the actual LSAT, you'll be breathing deeply and delivering plenty of oxygen to your brain.
Establish a regular sleep pattern
There's a good chance that you'll take the test in the morning. If so, then at least one month in advance start waking up early so that your brain is used to being conscious and working at that time. You should also consider doing your LSAT practice at the same time that you will take the actual test as well.

Focus on the test
If your mind is on other things, such as work, school, family, or other things, then you'll have trouble concentrating on the LSAT because your mind wanders. Try writing down all the things that you need to get done during the day, or within the next week and when specifically you will complete those. This will free up your mind to focus on the LSAT.
