My son did his secondary school studies abroad. We are now back in UK and he wants to apply for a course to become auto electrician. To do that he would need 4 GCSEs at grades 9 to 4 or equivalent. Now, I don't even know what that means as I too have done my studies abroad. Can anyone clarify for me what should my son do in order to get his GCSEs? Are there any part time or ecourses?
