Recently I started with Pimsleur Korean course, you can download it,it's usefull!!

Learn basic phrases next. It's amazing how often those are overlooked, but living in South Korea, I can tell you that you will use them very frequently. I would recommend focusing on learning the questions you will be asked. Some examples are: "Where are you from?" 어느 나라? This is a very informal variant that old Koreans ask me most often. 어디서 왔어요? Slightly more common, but they might drop the "서" part. How old are you? 몇 살이 에요? Age is very important in Korea, and I get asked this all the time. Can you speak Korean? 한국말 알아요? Literally, this means, "Do you know Korean?" 한국말 말해요? This one means, "Do you speak Korean?" There are two "Can you [verb]?" forms in Korean, but they are not very common in my experience. Koreans cut way more contextual corners than English, which is one reason I don't like many of the phrase books you can find. Many of them will teach you the expressions in ways you won't actually hear in Korea. Make sure you get audio for the expressions so you can practice sounding natural from the very beginning. If a phrase book is showing you phrases in formal Korean, like "한국말을 말 할 수가 있습니까?" AVOID IT. In my over three years of life in Korea and hundreds of encounters with Koreans who ask me questions in Korean, no one has ever asked me in that way.

You can go on you tube and look at videos Talk to me in Korean which does a good job of explaining points and fun to watch. There also Pit a Pat Korean which I got told on here which is good for explaining cultural points, vocab, and grammar. Watching K-dramas, reading manhwa's and listening to K-pop helps a lot to improve your Korean.

It depends on whether you prefer classroom instruction, online web courses (text only, text+ audio or video), PC software (audio only or with video) or online instruction by a live instructor. If you tell us your preferred learning style, people can better tell you what specific products they have benefited from.
