Protip: You have three choices -
Have a good social life and get bad grades since you're too busy partying and wasted to do anything
Have good grades and have no social life at all
Or have a moderate social life with pretty good grades.
Tips:
Do all your homework ASAP since the information you learned in class will still be around in your brain and you'll get it done faster without having to look through the books and you'll feel like a genius for remembering it. Then you'll see that question on that test and remember " OH YEH I REMEMBER WHEN I REMEMBERED DIS WHEN I DID MY HOMEOWRK" and you'll get A's.
Take simple notes. Only write down summaries, key points, things your teachers talk about etc, if your teacher doesn't talk about it at all, it probably won't be on the test but make sure you are familiar with it so your teacher doesn't pull a move on you. DO NOT USE HIGHLIGHTERS AND UNDERLINING STUFF WITH BOLD AND CRAP, THAT DOES NOT WORK, AT ALL. The best thing you can do is write neat notes and the night before, study for an hour, quiz your self, use a flash card program online that quizzes you like 5 different ways. Study each class for 30 minutes, go ahead a page or two so you'll feel like a genius is class when you get called on, significant events burn a hole in your mind and during the test you will remember feeling awesome. The night before a test, study for 60 minutes, if you are still unsure, write your notes out. DO NOT CRAM OR YOU WILL FAIL HARD. Go to bed early and get 10 hours of sleep.
Eat a bananna whilst studying and in the morning, the potassium is good for your brain. Eat whole grain cereals or eggs for breakfast, this will give you energy. Make sure you drink TONS of water. The reason why most people are tired in class even though they got enough sleep is because they aren't drinking enough water. Cells need water to perform crap, without water they can't do that stuff and make you tired. Divide your weight by two and that's the amount of OZ you should try to drink a day. Do not force the water down either or you will die.
For dinner, get cases of instant ramen and eat that stuff. I prefer not using the packets since they are literally salt and it's not healthy for you. Experiment with it, use different spices and stuff. Add an egg, some vegetables, and whatever spice you want. I like to add cumun / curry powder / ground red chili and taco seasoning and it tastes pretty awesome. I've had cinamon in it, tomato sauce, old bay, cheese, lemon and pepper, peppers etc, it's all pretty good so switch it up. You'll be suprised. If you don't like ramen, buy a sack of rice for about 20 dollars, make sure it's the good kind and add butter or anything you want. Be creative.
More to come!
