All students are engrossed in their work except you. How much longer should I wait? (sighs)

It's hard to say exactly how much longer you should wait, as it depends on the individual student and their work habits. However, if you've been waiting for a while and it seems like the student is not making progress, it may be a good idea to gently remind them to stay focused and on task. It's important to strike a balance between giving students the time they need to complete their work and ensuring that they are staying productive.

It would be best if you gave the students more time to complete their work. It is not productive to wait for them to finish if they are engrossed in their work. Instead, you should allow them to work at their own pace and provide support if they need it.
