No, during a lesson, you should engage in what the entire class is doing. If you do your own thing, it can distract other students and interfere with their learning. Additionally, if you do not participate in the lesson, you may miss important information and not understand the material, which can affect your future academic performance. Therefore, it's better to pay attention to the lesson and then do your own thing outside of class time.
