text: To begin with, one of the best adventage of online classes is flexibility. A student can usually take the course any time during the day or week. While there are custom essay writing and researching assigments to complete, the precise time to take the class often depends on the student's desire. Students who work are able to take the class based on their schedule. Many students work on afternoon. The flexibility makes it possible for a person to complete the course, while attending school or collage courses in person might be imposible due to their work schedules.
