Hey guys another length question n how long would it take me an English language native to learn Vietnamese?
What your goals actually are will make the difference in how long it will take to reach them , i mean the level you want to get to , but you will never stop learning, no mater how long you live so , .......forever
Learning a language is all about passion. People think learning Ukrainian is not only difficult because of its grammar, but because of its low quality course
