I am not sure how to respond to this. First, I was 13 as a freshman in HS and I was totally responsible in doing my work and actually skipped a grade during HS because the work was easy.

Is he going through any emotional crisis that distracts him?


But I agree with the teacher. He should be able to handle this without help. He is not far from college and you will not be there to quiz him when it gets even tougher.
