text: Why is taking a class better in the summer than during the school year? Classes tend to be less stressful during the summer than online classes during the school year because of summer break. Class during the school years are more stressful because sharing a online class with classes at school tends to build up stress which is not good for mentality. Students retaking a class over the summer is a good thing because it helps them relearn the main material that was learned from previous classes. It should also help the student know what they did wrong in the past and help them pass the class. This is a good thing because students can use the material they learned online and use it in the future.
