Article in English: When you have many classes or things to study for, it can seem hard to get through everything. Give yourself a schedule where you set specific times to study particular subjects. This makes studying seem less overwhelming, helping you to stay on task.  For example, you might decide to study biology for an hour on Monday night, followed by an hour of English. Then, on Tuesday afternoons, you study Math for two hours. Keep your schedule, but be flexible when needed. For example, if you have a biology exam coming up on Tuesday, you might study Biology for two hours on Monday night, and put English off for Tuesday. If you are studying around other people, post your schedule so they will know when it's not ok to distract you. A little variety keeps you refreshed and focused. If you try to study one thing for too long, your energy level and attention span will go way down. Switch things up to combat this. For instance, after two hours of Math, take a short break then switch to studying English. Distractions can actually be used in a positive way, and an incentive to get you through your studying. Say you need to study Geometry for an hour but keep getting distracted by funny cat videos. Tell yourself that if you get through the hour of studying without being distracted, you'll then let yourself watch all the cat videos you want.
