■ Real Korean, this time Have you ever started learning Korean through dramas, songs, or travel, only to stop along the way? LangTwo takes you from not knowing a single letter to forming sentences you can use today. Whether you’re a complete beginner or already know a little, you can start right where you are. ■ One lesson a day, one 15-day season [4 Hangul Lessons] Consonants, vowels, final consonants, and double consonants. Each lesson starts with a one-line explanation of the basic principle, then has you read and write the letters one by one before checking your understanding with a quiz. If you already know how to read Hangul, you can skip these lessons. [One Conversation Lesson a Day] One conversation you can use right away, such as “How much is it?”, “Where do you live?”, and “Would you like coffee or tea?” Listen, learn new words and grammar, practice speaking along, and check your understanding with a quiz. Ten minutes a day is all you need. [15-Day Season] Spend 15 days learning alongside people who started on the same day. Your medals add up each day, and when the season ends, you’ll receive a recap that gives you an at-a-glance view of what you’ve learned. ■ Put your voice side by side with a native speaker’s Record yourself reading the dialogue straight through, then listen to the native speaker and your own voice alternately, line by line. Your ears will notice how and where they differ before any explanation can. At the end of each lesson, check your understanding with a five-question quiz. For every question you get wrong, you’ll see a relevant pattern explained in one line right away. ■ Explanation languages Start with explanations in English. We’re preparing more explanation languages, including Chinese. ■ You can learn other languages too English, Spanish, Japanese, French, German, Italian, Chinese, Russian, Portuguese, Turkish, Dutch, Vietnamese, Indonesian, and Thai.
