Hi...please consult a Child Psychologist or a Psychologist.
And if possible get his Learning Style tested. We all have different learning styles and if we are taught in that style we learn better and easy.
Puberty (12 years old) is a difficult phase for most kids because their body, mind, and social experiences are changing rapidly and sometimes they face issues adjusting to this change, which may impact their academic performance as well.
Apart from this there might be other underlying issues which need to checked by a Psychologist. Do take minimum 4-5 sessions to understand his condition, as kids take time to develop trust before sharing their thoughts and emotions.
