don not take interest in studies and dont listen to me

hello har Preet I think this is a very common problem we all face it just try to feed ur child with love .most of the kids do such type of thing to attract your attention just involve in his activities wt he is doing became his partner in each n every activity you need a lot of patience while handling him once he thought that u are not only his Mother but also his friend he will easily share his problem with u he need ur time

Sometimes the way of teaching is such that the student fails to gain interest. For a few days, do not force him to study. But read books and do fun educational stuff maybe on the internet. Give him a lot of attention and find out what he is interested in doing. Then you can slowly ask him to read or study maybe for 15 to 20 mins. He will get back to it. You never know what the problem is. I am sure you have interacted with many boring teachers whose classes you refused to attend. I hope this is not something like that.

but the problem is i am working and come back at home near about 5 pm so i cant gve hm mre time

Absolutely understandable that you cannot give him more time. Then please find someone who can till you are back. Every child needs different levels of attention. You are the best judge for your child
