>> There is at least one English-only class at most schools. Some schools do Vietnamese in the mornings and English-only classes in the afternoon, while at other schools every class except Vietnamese Studies is taught in English.

Those are international schools. Their tuition are usually very high, and way out of the price range for most families in Vietnam. Normal schools where I live (Hanoi) only teach in Vietnamese.

We do have English class once or twice a week where we learn the basics of the language. But it does not provide us enough exposure to the language. To improve our language skills, we usually have to take extra classes after school.
