Adding exercise to your schedule may take some planning, but it won't be impossible. To get the benefits of the physical activity, schedule 150 minutes of exercise into your week. Adults should aim for at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity aerobic activity, or a combination of these. Adolescents should get at least 60 minutes of moderate or vigorous physical activity each day. There are so many activities you can do for aerobic exercise. You can join intramural sports teams, go for walks with friends, or hit your college's gym. Make sure to think about whether you are doing moderate or vigorous intensity workouts. Moderate physical activity includes brisk walking at three miles per hour or faster or bicycling slower than 10 miles per hour. You can also play doubles tennis, go ballroom dancing, or do general gardening. Vigorous intensity workouts include race walking, jogging, or running or cycling faster than 10 miles per hour. You can also swim laps, play singles tennis, do aerobic dancing, jump rope, or hike with a heavy backpack or uphill. Many gym classes provide excellent opportunities for vigorous and moderate exercise. Any aerobic activity should be performed for at least 10 minutes at a time to gain brain-boosting benefits. You should also spread it out throughout the week to keep your brain focused and sharp. Committing to an exercise program to help your studies may be difficult at first. Keep in mind the mental and cognitive benefits of the exercise and how it will help improve your school performance. Sit down and list all your commitments, activities, and study hours. Don't forget to list sleep times, meal times, and time for other things, like showering. Look for places you can incorporate exercise. Don't forget to count daily exercise. If you walk 10 or more minutes to class or work, this counts as aerobic physical activity. If you can start walking to class, make that one of your changes. Choose something that you believe you will enjoy and that can easily be placed into your schedule. If you have trouble finding time to workout, consider going out for a 30 minute jog or dancing around your room for half an hour. Breaking up exercises into smaller increments, such as three 10-minute fast-paced walks, can offer brain-boosting benefits if you struggle fitting exercise into your day. Consistent daily workouts, or workouts that coincide with your studying and classes, are more effective than trying to get 150 minutes of physical activity in on the weekend. The consistent physical activity throughout the week will boost your brain during the week, closer to when you study, instead of isolating it on the weekend. If you have class three times a week and study on those days, try to go for at least a 30 minute walk or jog before you go back to your room to study. If you go to school every day for eight hours, spend half an hour to an hour after school lets out doing something physical, then study after you get home. Exercise is great for relieving stress and reducing anxiety. Therefore, try not to make the physical activity a stressful part of your day. Allow yourself the time to take care of yourself. Remember, though you are not studying or working when you exercise, you are helping to boost your overall studying effectiveness. Listen to music while exercising. Numerous studies have linked music to stress relief and the reduction of anxiety. While out for your walk, listen to music that either relaxes you or makes you happy. Exercise with a friend. This can do two things at once: get physical activity into your day while letting you socialize, which can help boost your mood and reduce stress.

Summary: Determine an appropriate amount of exercise. Choose an aerobic exercise. Make time for your workout. Focus on consistency. Make the exercise an enjoyable experience.

In order to write, you will either need staff paper and a writing implement, such as a pencil or pen, or some kind of music writing software. Writing by hand is problematic because, in order to hear what you've played, you have to be able to play an instrument or you need to find someone else who can. With music notation software, you're able to hear what you've written immediately, using the computer playback. Some examples of music writing software include: Sibelius First, Finale and MagicScore Maestro. For free music writing software, try MuseScore and Lilypond. If you play or have access to an instrument, you can try playing your melodies using your instrument to hear how they sound before writing them down. Using the outline you created earlier, construct each individual movement. While writing, you'll need to be constantly making decisions regarding different musical techniques and styles within your piece. Some of those techniques include: Dynamics Rhythms Intervals Harmonies Theme development Counterpoint Voice leading Orchestration Traditionally, symphonies are written for the following instrumental types: strings (violin, viola, cello, and bass) woodwinds (2 flutes, 2 oboes, 2 clarinets, and 2 bassoons) brass (2 French horn, 2 trumpets with a small orchestra) and percussion (2 tympani, triangle, and cymbal) for a small orchestra. A medium size is when you can add a piccolo, English horn, bass clarinet, contra bassoon to the woodwinds and double the number of French horns and add 3 trombone plus a tuba to the brass as well as extra percussion instruments. If you can go larger, go for it. You don't however, have to stick with traditional instrumentation. If the instruments are available and there are players to play them, feel free to use other instruments in your symphony either adding them or using them like different colors (eg. replace one traditional instrument with one non-traditional one). For example, the inventor of the saxophone family designed his instruments for the orchestra (built in the keys of B and E) as well as the military band. You could also include an instrument that's been revived like one of the recorders, the viola da gamba or the oboe da caccia for example. Some symphonies also have vocal accompaniment. Try giving the same melodies to different instruments at different times to create a motif within the piece. Pay attention to layers and texture. There should never be any more than five layers happening at one time.

Summary: Gather your materials. Start writing. Assign melodies to different instruments.

The present value of the bond's principal tells you its current worth based on the current market interest rate. For this calculation, you need to know the current market interest rate. Also, you need to know the length of time until the bond expires and the number of interest payments per year. For example, suppose ABC Company issues 5-year, $500,000, 10% bonds. Interest is paid semi-annually. The current market interest rate is 12 percent. In this example, the current market interest rate is 12 percent. The length of time until the bond expires is 5 years. Divide the annual current market interest rate by the number of interest payments per year. Using the example above, the annual market interest rate is 12 percent. Interest payments are paid semi-annually, or twice per year. The market rate per period is 6 percent (.12/2=.06){\displaystyle (.12/2=.06)}. Multiply the number of interest payments per year by the number of years until the bond reaches maturity. This tells you how many interest payments will be made over the life of the bond. In the above example, interest is paid out semi-annually, or twice per year. The number of years until maturity is five. The total number of interest payments is 52=10{\displaystyle 5*2=10}. This is used to calculate the present value of the bond based on the current market interest rate. The formula for PVIF is 1/(1+r)n{\displaystyle 1/(1+r)^{n}}. In this formula, "r" is the interest rate per period. Also, "n" is the total number of interest payments. PVIF = 1/(1+.06)10=0.5584{\displaystyle 1/(1+.06)^{10}=0.5584} Present value of the principal = principal * PVIF $500,0000.5584=$279,200{\displaystyle \$500,000*0.5584=\$279,200}
Summary: Gather the information. Calculate the current market interest rate for each payment period. Calculate the total number of interest payments. Calculate the Present Value Interest Factor (PVIF).
