Don't go to online school. It's fake. There is a chat software like YY, which is taught by the teacher. I have been there. I have heard the names of phonetic symbols posted on the Internet, not the pronunciation. Those who learn Korean in YY chat software are all pronounced in Korean. To be clear, Korean and Korean are completely two languages. . It's just that the similar pronunciation and tone are completely different. .
If you really want to learn Korean, I suggest LZ go to a professional language training institution in his spare time. I used to take a class at Qingdao Seth Foreign Language School, which was very good. If LZ has time and enough money, it is best to study in Seoul. . Another point is pronunciation. Some people have studied Korean for 3 or 4 years and know that they are foreigners. Some people learn Korean 1 year, but they don't talk to Koreans. . When you have time, you can watch Korean dramas, learn from your favorite stars, and see how they say this sentence, under what circumstances and in what tone. . Frequent imitation will improve Korean pronunciation. . Then watch a passage or a line from a Korean drama by yourself, record it on tape, and compare it with TV to see what is uncertain. .
That's all I can say. I hope everything goes well. .
