Need help to pass IGCSE

I live in kuwait and My son is in grade 9 this year 2017/2018 and he is following IGCSE system in Pakistani school. I'm not happy with this school and I have 2 options for next years ( grade 10, 11 and 12):
1- I leave him in this school and give him private classes with good teachers after school
Or
2- shift him to New English School in kuwait but I need to make sure that the school is enough andI will not be in need to give private tuition
Please advise and share with me your experience with this school

Hi , you should know that whatever school your son will be , you will need to give him private lessons in almost all the subjects in year 10 and/or 11-12 , so to practice on how to answer past papers which is the most important issue in IGCSE examns, So you decide it yourself , depending on your abilities in all sides .Ofcourse NES is much better in education , but still I know a lot taking extra lessons . Some of them even leave NES at year 10 & go any average school or even home study to have more time .
