Need Basic School Information

Hi

I read somewhere that there is not a big difference between public and private (international) schools in Thailand (1 grade-12 grade). Only that the English level is higher at the private schools. Both of them should be following the same curriculum. I just wanted to know if that is true? Furthermore, I would like to know if public schools are free for Thai people? I know that private schools are very expensive, but do the charge the same for Thai and foreign people?

Furthermore, i would like to know what is the big difference between government schools, Thai private schools and international schools. Especially between thai private and government schools?

Additional questions

- Whenshould you sent your child to school i Thailand?, in Denmark you sent them from the age of 6.

- To proceed in the Thai educational system is previous school names important to procees to one of the good universities in Thailand? what I mean do the children which got an education from an international school have bigger chances for getting in good universities than e.g. children that haven't attendet international schools? Furthermore, I one is looking for well paid jobs do they look for high school grads and university grades or just university grades

I know that was a bit, but I hope you can help me
