The words “timetable” and “schedule” make most final year students want to eat their own vomit(呕吐物). Unfortunately, the harsh reality is that final year students must develop a timetable. If you don’t have a schedule or plan for studying, you will have no way of allocating your valuable time when the unexpected arises. A well-thought-out timetable can be a lifesaver. It is up to you to learn how to develop a schedule that meets your needs .Change it if necessary, but most important, follow it. All timetables should be made with the idea that they can be changed. A good one will keep you from wandering off course.

       A good timetable should make every hour count—every class, social event and other activity you engage in .You must focus on the other “free time” available and how you will use it. Make a weekly schedule and divided each day into one-hour increments. Indicate times for classes, socializing, and work time. Also block off a period for sleeping every day. In the precious hours left over, plan time for study. This gives you a rough road map of the time available. Of course, you can change your schedule as circumstances need.

       The timetable you develop should guide you in how to distribute the available time in the most productive manner. Sticking to your schedule can be tough, but don’t dribble away valuable time. Avoiding study is the easiest thing in the world. It is up to you to follow the schedule you’ve prepared. A good deal of your success in high school and with any future study depends on this simple truth.

       Remember, there is a learning curve. You learn the most in the first 30 minutes of study; after that, it progressively deteriorates（减弱）. After four or five hours of studying the same material in the same way, you are learning virtually nothing. The solution is to keep switching subjects and study styles.

Frederick M. Hess is the director of education policy studies in American. He says that a long summer vacation doesn't make sense in today's world.
In a summer vacation, millions of kids spend valuable time sending messages, watching TV, playing video games and doing shopping in the mall. These activities are putting their futures at risk.
Summer vacation once made sense in the past when you didn't need an education to get a good job. But now things have changed. For today's students, academic(学术的) skills are important to students' future success, but such skills are affected in the summertime. Most American schools offer up to thirteen weeks summer vacation.
Summer vacation also causes challenges for today's families. In the 1960s, more than 60% of families had a stay-at-home Mom. Now two-thirds of American children live in households where every adult works. For these families, summer vacation can be more burden than break. Someone must watch the kids.
“A longer school year does not have to be hard and boring work. Instead, it should allow teachers to give richer and more imaginative lessons,” Frederick M. Hess suggested, “Schools would have more time to devote to athletics, languages, music and the arts”.
Summer vacation can be a grand thing. But in the 21st century, it may also be outdated.
