Most schoolchildren spend too much time on assignments. But they can be performed much faster. It is enough to follow simple rules.
First of all, you need to learn how to plan your day. Decide on the tasks for the day and approximately calculate the time required for their implementation. Be sure to leave at least 1-1.5 hours for rest, then start assignment. You need to get used to doing assignment in the time defined for this task. In this case, you can use the alarm clock. Also with its help you can arrange breaks for 10-15 minutes every hour.
