Want a Better GMAT Score? Go to Sleep!
This is going to be a short post. It will also possibly have the biggest impact on your study of anything you do all day (or all month!).
When people ramp up to study for the GMAT, they typically find the time to study by cutting down on other activitiesno more Thursday night happy hour with the gang or Sunday brunch with the family until the test is over.
There are two activities, though, that you should never cutand, unfortunately, I talk to students every day who do cut these two activities. I hear this so much that I abandoned what I was going to cover today and wrote this instead. Were not going to cover any problems or discuss specific test strategies in this article. Were going to discuss something infinitely more important!
#1: You must get a full nights sleep
Period. Never cut your sleep in order to study for this test. NEVER.
Your brain does not work as well when trying to function on less sleep than it needs. You know this already. Think back to those times that you pulled an all-nighter to study for a final or get a client presentation out the door. You may have felt as though you were flying high in the moment, adrenaline coursing through your veins. Afterwards, though, your brain felt fuzzy and slow. Worse, you dont really have great memories of exactly what you didmaybe you did okay on the test that morning, but afterwards, it was as though youd never studied the material at all.
There are two broad (and very negative) symptoms of this mental fatigue that you need to avoid when studying for the GMAT (and doing other mentally-taxing things in life). First, when you are mentally fatigued, you cant function as well as normal in the moment. Youre going to make more careless mistakes and youre just going to think more slowly and painfully than usual.
Second, your brain continues to form new memories as you sleep. When you are trying to remember a bunch of new rules or solution strategies, you need good sleep to help cement that information in your long-term memory. In particular, when youre studying a bunch of new things at once, you need your memory to make strong and distinct memories. Otherwise, your memory wont be able to retrieve what you need, or itll mix up multiple memoriesand that obviously isnt what you want to happen on test day.
Many people arent getting adequate sleep even when theyre not taking on a challenge like the GMAT, and their lives are messier as a result. Make sleep a priority. Your brain will thank you.
#2: Exercise
Stick to your normal exercise routine, whatever that is. For some people, that means walking to do all of your errands and carrying things home, or cleaning the house. Some people play sports. Others hit the gym multiple times a week.
The point is to keep doing what you normally do; dont try to increase your study time by taking away from your second-best recharge time (after sleep). Exercise helps you to get rid of stress and generally gain a boost of energy. There's even a two-for-one bonus: regular exercise helps you sleep better at night.
Reward yourself
A bonus piece of advice. I started this post talking about giving up some regular social activities to make time for studying. You are going to have to make some sacrifices, of course, but dont become a hermit. You do need breaks and you do need to keep up with your social connections. When Im studying intensely, my rule is that Friday is a no-study zone. That day, I take a break and do something that I want to do.
(Friday also becomes my substitute day if Im burned out earlier in the week and want to skip a day of study. Thats finebut then I lose my day off on Friday. Sometimes, this motivates me to push through when Im feeling that I want to blow off my studies for a day. Other times, I do decide to study on Friday instead; if Im willing to do that, then I know my brain really does need the break right now.)
Good luck and happy studying!
