It is so important that students look over the notes we took in class each night. It refreshes their memories of classtime and it will make their homework assignments less difficult to complete. It will also help with their weekly quizzes. Consistency is key, so if they get in the habit of doing a little homework each night, then it will not be so overwhelming. The sames is true of studying. Just a few minutes set aside for each subject each night will contribute to their success in ALL subjects!
