A child is not allowed to study in grade 2 if he/she has not passed all required grade-1 subjects.
Is it correct to say
you won't pass your class if you don't pass all the required subjects
you won't pass your grade if you don't pass all the required subjects
I heard some Americans say "pass your class" but couldn't find that phrase in dictionaries and I am not sure if British people say that too.
I am wonder if "pass your grade" is correct.
What about "move up to higher grade"?
What is the phrase to express a student who didn't pass his class? For example, "he repeated his class", "he repeated his class twice"?
