no it is never too late. but if i were u, i may encourage him/her to learn phonetics now as he/she may be mature enough the way English sounds are combined.
Tks all of you !! I also think it is not too late for my daughter to learn phonics but it is difficult
to have spare time to take course since she is busy for homework.
Anyway, I start to search some course for her.
Pls recommend some courses and tutorial centre which are suitable for her junior level and age.
