I am a native English speaker learning Mandarin. For language learning I try to focus on learning new words in context. Rather than memorize lists of words, I try to learn them by using them in sentences. This helps if you are engaging in conversations with a friend as you can learn in the context of conversation. When I encounter a new word in Mandarin I try to create a number of sentences with that word, using it in the grammar structures I have previously learned, and in conversation with a friend. Once you learn a new word, try to use it as much as possible! I also use a flashcard program called Anki to help remember all the new vocabulary: www.ankisrs.net/ I hope this helps. Feel free to message me with any questions. Thanks!
