MANGODDENG( old version name )
It is recommended foreign language training method.
1. Listen to a foreign language and talk to a Mango Ding language application or site as you hear it.
2. Repeat 1 until my sentence matches the original sentence.
3. Investigate unknown words or idioms.
4. If you think you need it, check only what the pattern of the sentence is and what it means if the pattern is this way.
I do not recommend studying very detailed grammar as I do not think about the part of speech or grammar when I speak Korean.
