1. Reading more outside of class and the LSAT, even if it's just 10-20 minutes before bed it will increase your reading stamina as you do it more.

2. Better sleep. I don't just mean getting 7-9 hours, I also mean going to bed at the same time every night, waking up at the same time every morning, not eating within 3 hours of going to sleep, no screens within 1.5 hours of sleep (sleep is a big part of my major). A lot of people think they're getting good sleep because the quantity is high, even though the quality is low. This drastically helps with dedicated focuse.

3. Lastly, you could meditate. It's literally the practice of intentional focus, not the practice of thinking of nothing. Focus on one thing, stay focused on it (whether it be breathing, or staring at an object) then every time you begin to mentally wander try to catch yourself and revert your attention back to your stimuli. It trains your brain to stay on one topic for longer durations.

What I think made the Kumar example harder for me to grasp was there only being the stated condition of being 5+ minutes late.

For example if the statement said "A student will be cited as late, only if they arrive 5+ minutes after the homeroom bell, and they get caught by a teacher showing up past that time," then I could better understand that Kumar showing up 17 minutes late would not be logical, since we do not know if a teach found him showing up late.

Since there is only one condition states, 5+ minutes after the initial homeroom bell, Kumar hit all the provided necessary conditions, because there was only one condition. However if there were multiple necessary conditions, I think I would have gotten it.
