1. Set Goals
Having short-term and long-term goals is important in general, but in college it's crucial. For example, if you set the long-term goal of graduating with a 4.0, you automatically know how you have to proceed for the next 4 years. If you have a short-term of passing a test on a unit you didn't understand, then you know you need to set more time aside to study for it.
Prioritizing goes along with goal-setting. You need to think about what takes more or less time, what you're better or worse at, due dates, and the importance of the task. Once you take all of these things into consideration, you can begin to work on things in a way that is the most efficient for you.
As soon as you get an assignment, you should begin planning immediately. Look at the length, difficulty, and due date and space out times to work on different aspects. With an essay for example, maybe take a week to gather information, a day to set an outline, a couple days for a rough draft and another few for the finished product.
4. Write Things Down
When you begin to plan things, a planner or calendar is important to have. I use both a dry-erase calendar and a planner. It may seem redundant, but it keeps my tasks at hand always in my head or in reach. I use my planner to write down immediate tasks and plan out my homework every day. I personally like using a large planner with monthly and weekly pages for that reason. I also mark down all of the assignments and important days from my syllabi once I get them so I can always just flip ahead in my planner to check anything instead of searching through papers. Every month, I copy those dates onto my dry-erase calendar and I add any work hours. Then I begin a general to-do list for the month on an open note area to the side. For a boost of inspiration, I also add an inspirational quote. For ultra-organization, I suggest color coding different categories (e.g. school in red, work, in purple, and social obligations in blue). Continually seeing your tasks in 2 spots (or even just in a planner or calendar alone) will keep you from procrastinating.
5. You Can Say No
Sometimes it's hard to tell your friends that you can't do something, but if you don't have the time or energy for it, it's ok to say no. They'll understand - and if they don't, they're probably not good friends. You'll thank yourself in the long-run. You shouldn't add any extra stress if it isn't necessary.
6. Stay Focused
Try not to get distracted by your phone or social media etc. These things pull you away from important tasks you need to get done. If you want time to scroll through Instagram or watch Netflix, then set a time at night or a milestone you have to reach before you can do so. You'll feel less stressed and more rewarded. Also, if you're in an area where it's difficult to concentrate (such as a TV lounge), move to somewhere with less noise and distractions (like the library or study lounge).
7. Establish a Routine
They keep you focused, prioritized, and efficient.
8. If You're Doing Nothing, Do Something
If you're bored or if you have time in-between classes, do something. Utilize the extra time you have by getting small tasks done. Have 45 minutes before math class? Read the last chapter of that book for your English class.
9. Get Ahead
If you have the free-time, try to begin working on tasks ahead of time to avoid them piling up if anything doesn't go as planned.
10. Time-Management is a Myth
No matter how organized you are or how much work you do, there are still only 24 hours in a day and 7 days in a week. Time-management is actually more like self-management. You can't manage time, but you can always manage yourself. Understanding that will ease a lot of anxiety you may have.
