Summer School and Online Classes
        In the United States, summer school used to be seen mainly as a place for high school students to repeat classes they failed. But summer programs have expanded. Students often go to summer school so they can ease their class load during the school year. Another choice for many students is to take classes online. However, some online classes require students to come to a classroom to take tests. Students may also have to take part in group discussions with the teacher online. And there may be a required number of hours to spend logged on each day. Yet there may also be freedom to do the work anytime, day or night.
