Balancing College Life and Academics 1. Control Your Schedule; Don’t Let Your Schedule Control You Organization and time management skills are two of the most valuable skills you will ever have. One of the first things you should do at the beginning of each semester is organize the dates of all class tests and project deadlines from each syllabus, and all required meetings and events from each organization. All obligations should then be logged into a centralized schedule you keep at all times, such as a daily planner, desk calendar, or even a PDA (personal digital assistant). For the next 4 months, you now know exactly what you must schedule the rest of your life around. Next, it is highly recommended for you to set a schedule for yourself in writing to include all other items you want to create as a routine. Most importantly, this should include times of study, such as every Tuesday and Thursday from 3:30-6:30. Physically block off these time periods every Tuesday and Thursday for the rest of the semester. Of course, the most important part of creating a schedule is sticking to it! So, be disciplined enough to schedule any other activities that are less important around those that are most important. 2. Ask for Help When You Need It Whether it involves academics or organizational responsibilities, everyone comes to a point where they feel overwhelmed. This is what friends, fellow members, and other university resources are there for. Unfortunately, there are several reasons why people don’t seek help when it is available. Some people try to take on too ninth, trying to prove to themselves that "I can do this all on my own". Some may not want to admit to people that they "can’t handle everything." Others may feel they must do everything all on their own, because only then will they know it will get done right and on time (an early signal of being a control freak). Academically, seek out help when you don’t understand something. There should be plenty of resources available, from writing centers, to computer labs, to graduate assistants, to your professors who offer office hours. There are also other students who may understand that subject better, or who have even taken the course before. Especially in very large classes, some students may be intimidated to ask for help. But, the sole purpose of the institution and all of these resources is to help you learn. So use them. Ask for rope to be thrown down before you drown! 3. Keep a Firm Grasp on Your Priorities Understanding what your PRIORITIES are each and every day is one of the biggest keys to college success. It is also one of the easiest concepts to lose track of. It is a fast-paced world, where it is easy to become sidetracked with social activities, TV shows, video games, etc. Some people carry a card in their wallet, or even a card on their PC, where they list the top 1-5 priorities in their life. Everyone has exactly 24 hours each day. People who achieve more in life simply make better use of their 24 hours each day than everyone else. What you do with each of your 24 hours has as much to do with your success during college as an other factor. There is an old saying that "if it’s important enough to you, you make time for it." Be sure that nobody is in charge of your time except for you. It is one of the most valuable assets you have. 4. Don’t Wait Until the End of Your College Career to Stop Procrastinating (延迟) Whether it is an event or a semester project that is two months away, ask yourself each day "What can be done now instead of later" Write clown when you are going to do something, not simply when something is due. Set deadlines for yourself, and put them in writing. Then stick toil. Most people procrastinate because the activity they are supposed to do is not as desirable as what they would rather be doing. However, if you complete tasks early, you can enjoy your leisure time worry-free. This is one of the biggest ways to alleviate stress. If it is the 3rd day of the month, and there is a project due on the 28th of the month, most students hardly have that project on the radar screen vet. Then they see the project creep up on their calendar on the 24th or 25th, and they say "Uh-oh! "Further, they realize there is an event planned on the 26th, and they have to work at their part-time job on the 27th! This lack of planning is what leads to either missed deadlines, or turning a project in on time, but with poor quality. In addition to poor quality, it also led to undue stress for 4 days. One easy way to tackle projects ahead of time is to break the project down into several smaller ones. For example, instead of writing a 10-page paper in one night, write l-page per day for 10 days, or 1-page every other day. This will save time, increase quality, and decrease stress. 5. Go to Class That’s right. Skipping class is one of the most dangerous, yet tempting habits on college campuses today. Sure, you might be able to miss a class here and there—perhaps even miss a lot of classes—and still pass if you cram hard enough. However, don’t make things hard on your self, make things easy. The more you attend class, the less you have to study, and the more time you have for the everything else you want or need to do. Professors also have a way of telling you what will be on the test, and explaining the answers in class—but you are only privy to that if you are actually in class. Try to get in the habit of forcing yourself to sit in the FRONT of the class, especially in large classes. Studies show that students retain more information, and pay more attention, even if they don’t realize it. It also helps keep you awake. That usually allows you to take better notes, as well. 6. Find a Mentor or Example of a Great Student Lifer in Your Organization Almost every organization has one or more students who are shining examples of the balance between extra-curricular activities and academics. They make the Dean’s List every semester, hold an important office in the organization, work part-time, and even have a girlfriend or boyfriend. Everyone seems to ask "How do they do it" So, are they smarter than you In most cases, ABSOLUTELY NOT! There have been literally millions of college students that were "smart enough" to graduate, but who failed in the areas of time management, priorities, and responsibilities. So, understand the habits of those who are successful at balancing college life and academics. Ask them what their secrets are, and they will surely be willing to help. 7. Have Fun! Ok, so most college students don’t need help with this tip, right However, enjoy it while you can—you are only in college once! Many Americans recall their college days as tile best time of their life. Believe it or not, professors, administrators, and us college speakers want you to en enjoy every minute of it! Making efficient use of your time and controlling your schedule are important ingredients in being able to enjoy yourself. They allow you to alleviate stress and succeed both inside and outside the classroom, so you can have a BLAST during your college career. Good luck!
