It depends on the kid and on the type of “immersion” (for lack of a better word). I grew up in Romania in the ‘90s, when we had 2 hours of English per week starting with the 5th grade. I turned up fine when it comes to speaking/writing/reading the language, of course that I’ll always carry an accent when speaking it but I don’t care.
Looking back at it, after 3 decades, what helped me learn the language was that immersion I mentioned, i.e. I was watching English TV programs (Cartoon Network, Eurosport, MTV Europe) for a big part of the day, without that I wouldn’t have been able to pick it up so easily.
